According to the ACPI spec 9.1.1 _DSM (Device Specific Method),
intel_hid_dsm_fn_mask, acquired from function index 0, is "a buffer
containing one bit for each function index". When validitaing fn_index,
it should be compared with corresponding bit.
This buffer is usually longer than a byte. Depending on whether
INTEL_HID_DSM_HEBC_V2_FN exist, it could be either
"Buffer (0x02) { 0xFF, 0x01 }" or "Buffer (0x02) { 0xFF, 0x03 }".
Probably it won't grow larger according to the description. On older
platforms, available functions could be fewer or not supported at all,
i.e., "Buffer (One) { 0x00 }".

is a separate "R0L" BIOS for the i3/i5 based versions. This may also

The Yoga 11e series has 2 accelerometers described by a BOSC0200 ACPI node.
This setup relies on a Windows service which reads both accelerometers and
then calculates the angle between the 2 halves to determine laptop / tent /
tablet mode and then reports the calculated mode back to the EC by calling
special ACPI methods on the BOSC0200 node.
The bmc150 iio driver does not support this (it involves double
calculations requiring sqrt and arccos so this really needs to be done
in userspace), as a result of this on the Yoga 11e the thinkpad_acpi
code always reports SW_TABLET_MODE=0, starting with GNOME 3.38 reporting
SW_TABLET_MODE=0 causes GNOME to:
1. Not show the onscreen keyboard when a text-input field is focussed
with the touchscreen.
2. Disable accelerometer based auto display-rotation.
This makes sense when in laptop-mode but not when in tablet-mode. But
since for the Yoga 11e the thinkpad_acpi code always reports
SW_TABLET_MODE=0, GNOME does not know when the device is in tablet-mode.
Stop reporting the broken (always 0) SW_TABLET_MODE on Yoga 11e models
to fix this.
Note there are plans for userspace to support 360 degree hinges style
2-in-1s with 2 accelerometers and figure out the mode by itself, see:

Conventionally, wake-up events for a specific device, in our case the
lid device, are managed via the ACPI _PRW field. While this does not
seem strictly necessary based on ACPI spec, the kernel disables GPE
wakeups to avoid non-wakeup interrupts preventing suspend by default and
only enables GPEs associated via the _PRW field with a wake-up capable
device. This behavior has been introduced in commit f941d3e41d ("ACPI:
EC / PM: Disable non-wakeup GPEs for suspend-to-idle") and is described
in more detail in its commit message.
Unfortunately, on MS Surface devices, there is no _PRW field present on
the lid device, thus no GPE is associated with it, and therefore the GPE
responsible for sending the status-change notification to the lid gets
disabled during suspend, making it impossible to wake the device via the
lid.
This patch introduces a pseudo-device and respective driver which, based
on some DMI matching, marks the corresponding GPE of the lid device for
wake and enables it during suspend. The behavior of this driver models
the behavior of the ACPI/PM core for normal wakeup GPEs, properly
declared via the _PRW field.

Intel Platform Monitoring Technology is meant to provide a common way to
access telemetry and system metrics.
Register mappings are not provided by the driver. Instead, a GUID is read
from a header for each endpoint. The GUID identifies the device and is to
be used with an XML, provided by the vendor, to discover the available set
of metrics and their register mapping. This allows firmware updates to
modify the register space without needing to update the driver every time
with new mappings. Firmware writes a new GUID in this case to specify the
new mapping. Software tools with access to the associated XML file can
then interpret the changes.
The module manages access to all Intel PMT endpoints on a system,
independent of the device exporting them. It creates an intel_pmt class
to manage the devices. For each telemetry endpoint, sysfs files provide
GUID and size information as well as a pointer to the parent device the
telemetry came from. Software may discover the association between
endpoints and devices by iterating through the list in sysfs, or by looking
for the existence of the class folder under the device of interest. A
binary sysfs attribute of the same name allows software to then read or map
the telemetry space for direct access.

The UX360CA has a WMI device id 0x00060062, which reports whether the
lid is flipped in tablet mode (1) or in normal laptop mode (0).
Add a quirk (quirk_asus_use_lid_flip_devid) for devices on which this
WMI device should be used to figure out the SW_TABLET_MODE state, as
opposed to the quirk_asus_use_kbd_dock_devid.
Additionally, the device needs to be queried on resume and restore
because the firmware does not generate an event if the laptop is put to
sleep while in tablet mode, flipped to normal mode, and later awoken.
It is assumed other UX360* models have the same WMI device. As such, the
quirk is applied to devices with DMI_MATCH(DMI_PRODUCT_NAME, "UX360").
More devices with this feature need to be tested and added accordingly.
The reason for using an allowlist via the quirk mechanism is that the new
WMI device (0x00060062) is also present on some models which do not have
a 360 degree hinge (at least FX503VD and GL503VD from Hans' DSTS
collection) and therefore its presence cannot be relied on.

It may make sense to split the Microsoft Surface hardware platform
drivers out to a separate subdirectory, since some of it may be shared
between ARM and x86 in the future (regarding devices like the Surface
Pro X).
Further, newer Surface devices will require additional platform drivers
for fundamental support (mostly regarding their embedded controller),
which may also warrant this split from a size perspective.
This commit introduces a new platform/surface subdirectory for the
Surface device family, with subsequent commits moving existing Surface

Remove PSU EEPROM configuration for systems class equipped with
Mellanox chip Spectrume-2. Till now all the systems from this class
used few types of power units, all equipped with EEPROM device with
address space two bytes. Thus, all these devices have been handled by
EEPROM driver "24c32".
There is a new requirement is to support power unit replacement by "off
the shelf" device, matching electrical required parameters. Such device
could be equipped with different EEPROM type, which could be one byte
address space addressing or even could be not equipped with EEPROM.
In such case "24c32" will not work.

dev_dbg macro is used to dump the debug registers in resume from an S0ix
failure. However, when CONFIG_DYNAMIC_DEBUG is not set, the user may not be
able to find the debug dump on an S0ix failure which defeats the purpose.
The output of these messages is already controlled by a module parameter,
warn_on_s0ix_failures, making it a 2 step process to enable anyway when
CONFIG_DYNAMIC_DEBUG is set.
Hence, replace dev_dbg with dev_info, allowing the control of the messages
solely through the module parameter which is N by default.

slp_s0 counter value displayed via debugfs interface is calculated by
multiplying the granularity for crystal oscillator tick as 100us with
the value read from using slp_s0 offset. But the granularity of the tick
varies from platform to platform and it needs to be fixed.
Hence, specify granularity of the tick for each platform, so that the
value of the slp_s0 counter is accurate.

HP Spectre notebooks (and probably other model as well)
support up to 4 thermal policy:
- HP Recommended
- Performance
- Cool
- Quiet
at least on HP Spectre x360 Convertible 15-df0xxx the firmware sets the
thermal policy to default but hardcode the odvp0 variable to 1, this causes
thermald to choose the wrong DPTF profile witch result in low performance
when notebook is on AC, calling thermal policy write command allow firmware
to correctly set the odvp0 variable.

Pull another x86 platform driver fix from Hans de Goede:
"One final pdx86 fix for Tablet Mode reporting regressions (which make
the keyboard and touchpad unusable) on various Asus notebooks.
These regressions were caused by the asus-nb-wmi and the intel-vbtn
drivers both receiving recent patches to start reporting Tablet Mode /
to report it on more models.
Due to a miscommunication between Andy and me, Andy's earlier pull-req
only contained the fix for the intel-vbtn driver and not the fix for
the asus-nb-wmi code.
This fix has been tested as a downstream patch in Fedora kernels for
approx two weeks with no problems being reported"

platform/x86: asus-wmi: Fix SW_TABLET_MODE always reporting 1 on many different models
Commit b0dbd97de1 ("platform/x86: asus-wmi: Add support for
SW_TABLET_MODE") added support for reporting SW_TABLET_MODE using the
Asus 0x00120063 WMI-device-id to see if various transformer models were
docked into their keyboard-dock (SW_TABLET_MODE=0) or if they were
being used as a tablet.
The new SW_TABLET_MODE support (naively?) assumed that non Transformer
devices would either not support the 0x00120063 WMI-device-id at all,
or would NOT set ASUS_WMI_DSTS_PRESENCE_BIT in their reply when querying
the device-id.
Unfortunately this is not true and we have received many bug reports about
this change causing the asus-wmi driver to always report SW_TABLET_MODE=1
on non Transformer devices. This causes libinput to think that these are
360 degree hinges style 2-in-1s folded into tablet-mode. Making libinput
suppress keyboard and touchpad events from the builtin keyboard and
touchpad. So effectively this causes the keyboard and touchpad to not work
on many non Transformer Asus models.
This commit fixes this by using the existing DMI based quirk mechanism in
asus-nb-wmi.c to allow using the 0x00120063 device-id for reporting
SW_TABLET_MODE on Transformer models and ignoring it on all other models.

on the 9 / "Laptop" chasis-type")
1fac39fd03 ("platform/x86: intel-vbtn: Also handle tablet-mode switch on
"Detachable" and "Portable" chassis-types")
Enabled reporting of SW_TABLET_MODE on more devices since the vbtn ACPI
interface is used by the firmware on some of those devices to report this.
Testing has shown that unconditionally enabling SW_TABLET_MODE reporting
on all devices with a chassis type of 8 ("Portable") or 10 ("Notebook")
which support the VGBS method is a very bad idea.
Many of these devices are normal laptops (non 2-in-1) models with a VGBS
which always returns 0, which we translate to SW_TABLET_MODE=1. This in
turn causes userspace (libinput) to suppress events from the builtin
keyboard and touchpad, making the laptop essentially unusable.
Since the problem of wrongly reporting SW_TABLET_MODE=1 in combination
with libinput, leads to a non-usable system. Where as OTOH many people will
not even notice when SW_TABLET_MODE is not being reported, this commit
changes intel_vbtn_has_switches() to use a DMI based allow-list.
The new DMI based allow-list matches on the 31 ("Convertible") and
32 ("Detachable") chassis-types, as these clearly are 2-in-1s and
so far if they support the intel-vbtn ACPI interface they all have
properly working SW_TABLET_MODE reporting.
Besides these 2 generic matches, it also contains model specific matches
for 2-in-1 models which use a different chassis-type and which are known
to have properly working SW_TABLET_MODE reporting.
This has been tested on the following 2-in-1 devices:
Dell Venue 11 Pro 7130 vPro
HP Pavilion X2 10-p002nd
HP Stream x360 Convertible PC 11
Medion E1239T

A struct device is a dynamic structure, with reference counting.
"Tricking" the kernel to make a dynamic structure static, by working
around the driver core release detection logic, is not nice.
Because of this, this code has been used as an example for others on
"how to do things", which is just about the worst thing possible to have
happen.
Fix this all up by making the platform device dynamic and providing a
real release function.

Commit cfae58ed68 ("platform/x86: intel-vbtn: Only blacklist
SW_TABLET_MODE on the 9 / "Laptop" chasis-type") restored SW_TABLET_MODE
reporting on the HP stream x360 11 series on which it was previously broken
by commit de9647efea ("platform/x86: intel-vbtn: Only activate tablet
mode switch on 2-in-1's").
It turns out that enabling SW_TABLET_MODE reporting on devices with a
chassis-type of 10 ("Notebook") causes SW_TABLET_MODE to always report 1
at boot on the HP Pavilion 11 x360, which causes libinput to disable the
kbd and touchpad.
The HP Pavilion 11 x360's ACPI VGBS method sets bit 4 instead of bit 6 when
NOT in tablet mode at boot. Inspecting all the DSDTs in my DSDT collection
shows only one other model, the Medion E1239T ever setting bit 4 and it
always sets this together with bit 6.
So lets treat bit 4 as a second bit which when set indicates the device not
being in tablet-mode, as we already do for bit 6.
While at it also prefix all VGBS constant defines with "VGBS_".

The WMI INIT method on for some reason turns on the camera LED on these
2-in-1s, without the WMI interface allowing further control over the LED.
To fix this commit b5f7311d3a ("platform/x86: asus-nb-wmi: Do not load
on Asus T100TA and T200TA") added a blacklist with these 2 models on it
since the WMI driver did not add any extra functionality to these models.
Recently I've been working on making more 2-in-1 models report their
tablet-mode (SW_TABLET_MODE) to userspace; and I've found that these 2
Asus models report this through WMI. This commit reverts the adding
of the blacklist, so that the Asus WMI driver can be used on these
models to report their tablet-mode. I have another patch fixing the LED
issue in a different manner.
Note this is the second time the we revert the adding of the
asus_nb_wmi_blacklist. It was reverted before in commit:
aab9e7896e ("platform/x86: asus-nb-wmi: Revert "Do not load on Asus

But some how (accidentally re-applying of the patch?) it got re-added
again in commit 3bd12da7f5 ("platform/x86: asus-nb-wmi: Do not load

As part of this update, change the error handling inside
cros_ec_get_sensor_count() such that the legacy LPC interface is tried
on all error values, not just when msg->result != EC_RESULT_SUCCESS.
Note that there is a slight change in API in cros_ec_get_sensor_count():
it will return a negative number of sensors when there are no sensors
on arm platform when MOTIONSENSE_CMD_DUMP is not supported (typical for
sensorless chromebook) instead of 0. However, this is not a problem when
probing the EC as we ignore errors only looking for cros_ec_get_sensor_count()
returning a positive number of sensors.

Commit 696c6523ec ("platform/x86: thinkpad_acpi: add mapping for new

clipping/snipping tool hotkey got ignored because there was no good
key-code to map it to.
Recently a new KEY_SELECTIVE_SCREENSHOT keycode was added by commit
3b059da983 ("Input: allocate keycode for "Selective Screenshot" key")
quoting from the commit message:
"New Chrome OS keyboards have a "snip" key that is basically a selective
screenshot (allows a user to select an area of screen to be copied).
Allocate a keycode for it."
Support for this "snip" key seems like it is also a good match for the
clipping/snipping tool hotkey, so map this hotkey to the new
KEY_SELECTIVE_SCREENSHOT key-code.

F10: Has a symbol of a telephone horn which has been picked up from the

flow for configuring a device connected to a typeC port is as below:
1. Source/sink detection
2. Orientation
3. Data role
4. VCONN
5. VBUS (USB Type-C currents)
6. The connector is now configured. We can start the PD communication
that should lead into configuration of the mux if we enter a mode.
But in existing code data role was set after the connector and mux are
already configured. So fix this by following the spec to set the data

The EC reports a variety of error codes. Most of those, with the exception
of EC_RES_INVALID_VERSION, are converted to -EPROTO. As result, the actual
EC error code gets lost. Introduce cros_ec_map_error() to map EC error
codes to Linux error codes, and use it in cros_ec_cmd_xfer_status() to
report more meaningful errors to the caller. With this change, callers of
cros_ec_cmd_xfer_status() can implement a more distinguished action without
having to rely on the EC error code. At the same time, debugging is improved
in situations where the Linux error code is reported to userspace and/or in
the kernel log.

Here is the large set of Staging and IIO driver patches for 5.9-rc1.
Lots of churn here, but overall the size increase in lines added is
small, while adding a load of new IIO drivers.
Major things in here:
- lots and lots of IIO new drivers and frameworks added
- IIO driver fixes and updates
- lots of tiny coding style cleanups for staging drivers
- vc04_services major reworks and cleanups
We had 3 set of drivers move out of staging in this round as well:
- wilc1000 wireless driver moved out of staging
- speakup moved out of staging
- most USB driver moved out of staging
Full details are in the shortlog.
All of these have been in linux-next with no reported issues. The last
few changes here were to resolve reported linux-next issues, and they
seem to have resolved the problems.

static priority level knowledge from non-scheduler code.
The three APIs for non-scheduler code to set SCHED_FIFO are:
- sched_set_fifo()
- sched_set_fifo_low()
- sched_set_normal()
These are two FIFO priority levels: default (high), and a 'low' priority level,
plus sched_set_normal() to set the policy back to non-SCHED_FIFO.
Since the changes affect a lot of non-scheduler code, we kept this in a separate
tree.
When merging to the latest upstream tree there's a conflict in drivers/spi/spi.c,
which can be resolved via:
sched_set_fifo(ctlr->kworker_task);

mlxbf-tmfifo accesses config space using native types -
which works for it since the legacy virtio native types.
This will break if it ever needs to support modern virtio,
so with new tags previously introduced for virtio net config,
sparse now warns for this in drivers.
Since this is a legacy only device, fix it up using
virtio_legacy_is_little_endian for now.

As with cros_ec_cmd_xfer_status(), etc., it's not enough to simply check
for the return status of send_command() -- that only covers transport or
other similarly-fatal errors. One must also check the ->result field, to
see whether the command really succeeded. If not, we can't use the data
it returns.
The caller of cros_ec_get_host_event_wake_mask() ignores this, and so
for example, on EC's where the command is not implemented, we're using
junk (or in practice, all zeros) for our wake-mask. We should be using a
non-zero default (currently, it's supposed to be all-1's).
Fix this by checking the ->result field and returning -EPROTO for
errors.
I might label this as fixing commit 29d99b966d ("cros_ec: Don't signal
wake event for non-wake host events"), except that this fix alone
actually may make things worse, as it now allows for a lot more spurious
wakeups. The patch "platform/chrome: cros_ec_proto: ignore battery/AC
wakeups on old ECs" helps to mitigate this.
Signed-off-by: Brian Norris <briannorris@chromium.org>
Signed-off-by: Enric Balletbo i Serra <enric.balletbo@collabora.com>
ECs that don't implement EC_CMD_HOST_EVENT_GET_WAKE_MASK should still
have some reasonable default mask -- otherwise, they'll treat a variety
of EC signals as spurious wakeups. Battery and AC events can be
especially common, for devices that have been sitting at full charge
plugged into AC for a long time, as they may cycle their charging off
and on, or their battery may start reporting failures as it ages.
Treating these as wakeups does not serve a useful purpose, and is
instead often counterproductive. And indeed, later ECs (that implement
the mask) don't include these events in their wake-mask.
Note that this patch doesn't do anything without the subsequent patch
("platform/chrome: cros_ec_proto: check for missing
EC_CMD_HOST_EVENT_GET_WAKE_MASK"), because
cros_ec_get_host_event_wake_mask() currently does not return an error if
EC_CMD_HOST_EVENT_GET_WAKE_MASK is not implemented.
Some additional notes:
While the EC typically knows not to wake the CPU for these unimportant
events once the CPU reaches a sleep state, it doesn't really have a way
to know that the CPU is "almost" asleep, unless it has support for
EC_CMD_HOST_SLEEP_EVENT. Alas, these older ECs do not support that
command either, so this solution is not 100% complete.

On some machines (nami), interrupt latency cause samples to appear
to be from the future and are pegged to the current time.
We would see samples with this pattern:
[t, t + ~5ms, t + ~10ms, t + ~10ms + 100us, t + ~10ms + 200us],
(current now) (current now)
(t is the last timestamp time)
Last 2 samples would be barely spread, causing applications to
complain.
We now spread the entire sequence. This is not great: in the example
the sensor was supposed to send samples every 5ms, it now appears to
send one every 2.5ms, but it is slightly closer to reality:

When port update is called during probe(), any error with setting the
Type C muxes results in an errno being returned to probe(), which promptly
returns that itself. Ensure that we unregister any registered partners
when doing so, to prevent orphaned partners on the Type C connector
class framework.
Move the cros_typec_add_partner() and cros_typec_remove_partner() code
together to higher up in the file, so that they are together, and we can
call cros_typec_remove_partner() from cros_unregister_ports().

Merge 5.8-rc6 into staging-next
We need the staging fixes in here, and it resolves a merge issue with an
iio driver.
Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
Some new devices, but particularly good this time is the core rework coming
from Alexandru. Some of this has been in Analog's tree a long time, but other
parts are motivated by closing down common mistakes in new drivers.
Changes since first try at this pull request:
* Add missed patch to actually remove iio_priv_to_dev and as a result
also drop a few ingenic patches that need to be updated to take this
into account.
* Fix an ordering issue int he pollfunc attach in the core rework.
New device support
* qcom pmic7 adc
- New driver using common qcom-vadc library. Some associated cleanups and
refactors.
* invensense icm42600
- New driver supporting icm42600, icm42602, icm42605 and icm42622 via i2c
or spi. These are all 6 axis IMUs with gyro and accelerometers.
Driver supports buffered modes using the hardware fifo and interpolation
for accurate timestamps.
* sensirion scd30
- New driver for this carbon dioxide sensor including i2c and serial
interfaces + bindings.
Features
* ak8975
- Add reset gpio support.

* ingenic-adc -convert to yaml.
Core rework all carried through by Alexandru Ardelean.
* Assign parent device in the core rather than every driver. A few devices
need to provide specific non standard parents, so there is support for
overriding.
* Start to take parts of struct iio_dev opaque to the drivers.
This will be a long term job, but should reduce the number of drivers
we get that use parts that are currently only 'internal' by documentation.
* Move attach and detach of pollfunc to the core. Every triggered buffer
using driver had to do the same thing, so lets do it in the core. The
hard part here was getting all the drivers into canonical form so there
would be no functional changes in this final patch. That's taken quite
a lot of work over last couple of cycles!

Using uninitialized_var() is dangerous as it papers over real bugs[1]
(or can in the future), and suppresses unrelated compiler warnings
(e.g. "unused variable"). If the compiler thinks it is uninitialized,
either simply initialize the variable or make compiler changes.
In preparation for removing[2] the[3] macro[4], remove all remaining
needless uses with the following script:
git grep '\buninitialized_var\b' | cut -d: -f1 | sort -u | \
xargs perl -pi -e \
's/\buninitialized_var\(([^\)]+)\)/\1/g;
s:\s*/\* (GCC be quiet|to make compiler happy) \*/$::g;'
drivers/video/fbdev/riva/riva_hw.c was manually tweaked to avoid
pathological white-space.
No outstanding warnings were found building allmodconfig with GCC 9.3.0
for x86_64, i386, arm64, arm, powerpc, powerpc64le, s390x, mips, sparc64,

This reverts commit 5037d4ddda.
Explanation why this does not work:
This change connects the simswap to the LED subsystem of the kernel.
From my point of view, it's nonsense. If we do it this way, then this
can be switched relatively easily via the LED subsystem (trigger:
none/default-on) and that is dangerous! If this is used, it would be
unfavorable, since there is also another trigger (trigger:
heartbeat/netdev).
Therefore, this simswap GPIO should remain in the GPIO
subsystem and be switched via it and not be connected to the LED
subsystem. To avoid the problems mentioned above. The LED subsystem is
not made for this and it is not a good compromise, but rather dangerous.

Many Bay Trail and Cherry Trail devices come with a camera attached to
Intel's Image Signal Processor. Linux currently does not have a driver for
these, so they do not work as a camera.
Some of these camera's have a status LED which is controlled through a GPIO
in some cases, e.g. on the Asus T100TA and Asus T200TA, there is a firmware
issue where the LED gets turned on at boot.
This commit adds a Linux LED driver for the camera LED on these devices.
This driver will turn the LED off at boot and also allows controlling the
LED (so the user can repurpose it) through the sysfs LED interface.
Which GPIO is attached to the LED is usually not described in the ACPI
tables, so this driver contains per-system info about the GPIO inside the
driver. This means that this driver only works on systems the driver knows
about.

Use thermal_zone_device_{en|dis}able() and thermal_zone_device_is_enabled().
Consequently, all set_mode() implementations in drivers:
- can stop modifying tzd's "mode" member,
- shall stop taking tzd's lock, as it is taken in the helpers
- shall stop calling thermal_zone_device_update() as it is called in the
helpers
- can assume they are called when the mode truly changes, so checks to
verify that can be dropped
Not providing set_mode() by a driver no longer prevents the core from
being able to set tzd's mode, so the relevant check in mode_store() is
removed.
Other comments:
- acpi/thermal.c: tz->thermal_zone->mode will be updated only after we
return from set_mode(), so use function parameter in thermal_set_mode()
instead, no need to call acpi_thermal_check() in set_mode()
- thermal/imx_thermal.c: regmap writes and mode assignment are done in
thermal_zone_device_{en|dis}able() and set_mode() callback
- thermal/intel/intel_quark_dts_thermal.c: soc_dts_{en|dis}able() are a
part of set_mode() callback, so they don't need to modify tzd->mode, and
don't need to fall back to the opposite mode if unsuccessful, as the return
value will be propagated to thermal_zone_device_{en|dis}able() and
ultimately tzd's member will not be changed in thermal_zone_device_set_mode().
- thermal/of-thermal.c: no need to set zone->mode to DISABLED in
of_parse_thermal_zones() as a tzd is kzalloc'ed so mode is DISABLED anyway

The change passes the parent device to the iio_device_alloc() call. This
also updates the devm_iio_device_alloc() call to consider the device object
as the parent device by default.
Having it passed like this, should ensure that any IIO device object
already has a device object as parent, allowing for neater control, like
passing the 'indio_dev' object for other stuff [like buffers/triggers/etc],
and potentially creating iiom_xxx(indio_dev) functions.
With this patch, only the 'drivers/platform/x86/toshiba_acpi.c' needs an
update to pass the parent object as a parameter.
In the next patch all devm_iio_device_alloc() calls will be handled.

Pull i2c updates from Wolfram Sang:
"I2C has quite some patches for you this time. I hope it is the move to
per-driver-maintainers which is now showing results. We will see.
The big news is two new drivers (Nuvoton NPCM and Qualcomm CCI),
larger refactoring of the Designware, Tegra, and PXA drivers, the
Cadence driver supports being a slave now, and there is support to
instanciate SPD eeproms for well-known cases (which will be
user-visible because the i801 driver supports it), and some
devm_platform_ioremap_resource() conversions which blow up the
diffstat.
Note that I applied the Nuvoton driver quite late, so some minor fixup
patches arrived during the merge window. I chose to apply them right
away because they were trivial"

Since commit 84af7a6194 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.
This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.
There are a variety of indentation styles found.
a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)
f) 1 tab + 1 space + '---help---'
g) 1 tab + 2 spaces + '---help---'
In order to convert all of them to 1 tab + 'help', I ran the
following commend:
$ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

Merge tag 'media/v5.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab:
- Media documentation is now split into admin-guide, driver-api and
userspace-api books (a longstanding request from Jon);
- The media Kconfig was reorganized, in order to make easier to select
drivers and their dependencies;
- The testing drivers now has a separate directory;
- added a new driver for Rockchip Video Decoder IP;
- The atomisp staging driver was resurrected. It is meant to work with
4 generations of cameras on Atom-based laptops, tablets and cell
phones. So, it seems worth investing time to cleanup this driver and
making it in good shape.
- Added some V4L2 core ancillary routines to help with h264 codecs;
- Added an ov2740 image sensor driver;
- The si2157 gained support for Analog TV, which, in turn, added
support for some cx231xx and cx23885 boards to also support analog
standards;
- Added some V4L2 controls (V4L2_CID_CAMERA_ORIENTATION and
V4L2_CID_CAMERA_SENSOR_ROTATION) to help identifying where the camera
is located at the device;
- VIDIOC_ENUM_FMT was extended to support MC-centric devices;
- Lots of drivers improvements and cleanups.

On the ASUS laptop UX325JA/UX425JA, most of the media keys are not
working due to the ASUS WMI driver fails to be loaded. The ACPI error
as follows leads to the failure of asus_wmi_evaluate_method.
ACPI BIOS Error (bug): AE_AML_BUFFER_LIMIT, Field [IIA3] at bit offset/length 96/32 exceeds size of target Buffer (96 bits) (20200326/dsopcode-203)

ACPI Error: Aborting method \_SB.ATKD.WMNB due to previous error (AE_AML_BUFFER_LIMIT) (20200326/psparse-531)
The DSDT for the WMNB part shows that 5 DWORD required for local
variables and the 3rd variable IIA3 hit the buffer limit.

}
The limitation is determined by the input acpi_buffer size passed
to the wmi_evaluate_method. Since the struct bios_args is the data
structure used as input buffer by default for all ASUS WMI calls,
the size needs to be expanded to fix the problem.

The HP Stream x360 11-p000nd no longer report SW_TABLET_MODE state / events
with recent kernels. This model reports a chassis-type of 10 / "Notebook"
which is not on the recently introduced chassis-type whitelist
Commit de9647efea ("platform/x86: intel-vbtn: Only activate tablet mode
switch on 2-in-1's") added a chassis-type whitelist and only listed 31 /
"Convertible" as being capable of generating valid SW_TABLET_MOD events.
Commit 1fac39fd03 ("platform/x86: intel-vbtn: Also handle tablet-mode
switch on "Detachable" and "Portable" chassis-types") extended the
whitelist with chassis-types 8 / "Portable" and 32 / "Detachable".
And now we need to exten the whitelist again with 10 / "Notebook"...
The issue original fixed by the whitelist is really a ACPI DSDT bug on
the Dell XPS 9360 where it has a VGBS which reports it is in tablet mode
even though it is not a 2-in-1 at all, but a regular laptop.
So since this is a workaround for a DSDT issue on that specific model,
instead of extending the whitelist over and over again, lets switch to
a blacklist and only blacklist the chassis-type of the model for which
the chassis-type check was added.
Note this also fixes the current version of the code no longer checking
if dmi_get_system_info(DMI_CHASSIS_TYPE) returns NULL.

Now that pstore_register() can correctly pass max_reason to the kmesg
dump facility, introduce a new "max_reason" module parameter and
"max-reason" Device Tree field.
The "dump_oops" module parameter and "dump-oops" Device
Tree field are now considered deprecated, but are now automatically
converted to their corresponding max_reason values when present, though
the new max_reason setting has precedence.
For struct ramoops_platform_data, the "dump_oops" member is entirely
replaced by a new "max_reason" member, with the only existing user
updated in place.
Additionally remove the "reason" filter logic from ramoops_pstore_write(),
as that is not specifically needed anymore, though technically
this is a change in behavior for any ramoops users also setting the
printk.always_kmsg_dump boot param, which will cause ramoops to behave as

Setting the initial state of input-device switches must be done before
registering the input-device.
Otherwise the initial state will get send out as an event as soon
as input_sync() gets called.
E.g. when undocking a tablet using intel-vbtn to report SW_TABLET_MODE
and SW_DOCK before this commit we would get (evemu-record output):
E: 0.000001 0005 0005 0001 # EV_SW / SW_DOCK 1
E: 0.000001 0000 0000 0000 # ------------ SYN_REPORT (0) ---------- +0ms
E: 0.000109 0005 0005 0000 # EV_SW / SW_DOCK 0

On some Asus devices, e.g. the T100TA, when the charger is connected
we not only get a WMI event with code 0x58, but immediately after that
event we also get an even with code 0x79.
This is likely related to these devices having an Asus WMI device with a
device-id of 0x00120066, which seems to provide some sort of charger-type
info. The T100TA charger over a micro-USB connector, the embedded-
controller register read when calling asus_wmi_get_devstate(0x00120066)
returns different values when connected to a USB port (max 500mA charging)
vs when connected to a 2A capable wall-charger. But the AML code reading
this mangles the return value so that we can no longer tell the difference.
So for now the meaning of the value return when getting the status of
device-id 0x00120066 is unclear.
This commit adds a key-mapping of code 0x79 to KE_IGNORE, silencing the
kernel logging the following message every time the charger is plugged-in:

The WMI INIT method on for some reason turns on the camera LED on these
2-in-1s, without the WMI interface allowing further control over the LED.
To fix this commit b5f7311d3a ("platform/x86: asus-nb-wmi: Do not load
on Asus T100TA and T200TA") added a blacklist with these 2 models on it
since the WMI driver did not add any extra functionality to these models.
Recently I've been working on making more 2-in-1 models report their
tablet-mode (SW_TABLET_MODE) to userspace; and I've found that these 2
Asus models report this through WMI. This commit reverts the adding
of the blacklist, so that the Asus WMI driver can be used on these
models to report their tablet-mode.
Note, not calling INIT is also not an option, because then we will not
receive events when the tablet-mode changes. So the LED issue will need
to be fixed somewhere else entirely.

Commit de9647efea ("platform/x86: intel-vbtn: Only activate tablet mode
switch on 2-in-1's") added a DMI chassis-type check to avoid accidentally
reporting SW_TABLET_MODE = 1 to userspace on laptops.
Some devices with a detachable keyboard and using the intel-vbnt (INT33D6)
interface to report if they are in tablet mode (keyboard detached) or not,
report 32 / "Detachable" as chassis-type, e.g. the HP Pavilion X2 series.
Other devices with a detachable keyboard and using the intel-vbnt (INT33D6)
interface to report SW_TABLET_MODE, report 8 / "Portable" as chassis-type.
The Dell Venue 11 Pro 7130 is an example of this.
Extend the DMI chassis-type check to also accept Portables and Detachables
so that the intel-vbtn driver will report SW_TABLET_MODE on these devices.
Note the chassis-type check was originally added to avoid a false-positive
tablet-mode report on the Dell XPS 9360 laptop. To the best of my knowledge
that laptop is using a chassis-type of 9 / "Laptop", so after this commit
we still ignore the tablet-switch for that chassis-type.

reporting SW_TABLET_MODE = 1 to userspace on laptops (specifically on the
Dell XPS 9360), to avoid e.g. userspace ignoring touchpad events because
userspace thought the device was in tablet-mode.
But if we are not getting the initial status of the switch because the
device does not have a tablet mode, then we really should not advertise

Slim Bootloader(SBL) is a small open-source boot firmware,
designed for running on certain Intel platforms. SBL can be
thought-of as fulfilling the role of a minimal BIOS
implementation, i.e initializing the hardware and booting
Operating System.
Since SBL is not UEFI compliant, firmware update cannot be triggered
using standard UEFI runtime services. Further considering performance
impact, SBL doesn't look for a firmware update image on every reset
and does so only when firmware update signal is asserted.
SBL exposes an ACPI-WMI device which comes up in sysfs as
/sys/bus/wmi/44FADEB1xxx and this driver adds a
"firmware_update_request" device attribute. This attribute normally
has a value of 0 and userspace can signal SBL to update firmware,
on next reboot, by writing a value of 1 like:
echo 1 > /sys/bus/wmi/devices/44FADEB1xxx/firmware_update_request
This driver only implements a signaling mechanism, the actual firmware
update process and various details like firmware update image format,
firmware image location etc are defined by SBL and are not in the
scope of this driver.

asus-nb-wmi does not add any extra functionality on these Asus
Transformer books. They have detachable keyboards, so the hotkeys are
send through a HID device (and handled by the hid-asus driver) and also
the rfkill functionality is not used on these devices.
Besides not adding any extra functionality, initializing the WMI interface
on these devices actually has a negative side-effect. For some reason
the \_SB.ATKD.INIT() function which asus_wmi_platform_init() calls drives
GPO2 (INT33FC:02) pin 8, which is connected to the front facing webcam LED,
high and there is no (WMI or other) interface to drive this low again
causing the LED to be permanently on, even during suspend.
This commit adds a blacklist of DMI system_ids on which not to load the
asus-nb-wmi and adds these Transformer books to this list. This fixes

This adds dual fan control for the following models:
P50, P51, P52, P70, P71, P72, P1 gen1, P2 gen2, X1E gen1 and X1E gen2.
Both fans are controlled together as if they were a single fan.
Tested on an X1 Extreme Gen1, an X1 Extreme Gen2, and a P50.
The patch is defensive, it adds only specific supported machines, and falls
back to the old behavior if both fans cannot be controlled.
Background:
I tested the BIOS default behavior on my X1E gen2 and both fans are always
changed together. So rather than adding controls for each fan, this controls
both fans together as the BIOS would do.
This was inspired by a discussion on dual fan support for the thinkfan tool
(see link below). All BIOS IDs are taken from there. The X1E gen2 ID is
verified on my machine.
Thanks to GitHub users voidworker and civic9 for the earlier patches and
BIOS IDs, and to users peter-stoll and sassman for testing the patch on
their machines.

This driver only creates a bunch of platform devices sharing resources
belonging to the PMC device. This is pretty much what MFD subsystem is
for so move the driver there, renaming it to intel_pmc_bxt.c which
should be more clear what it is.
MFD subsystem provides nice helper APIs for subdevice creation so
convert the driver to use those. Unfortunately the ACPI device includes
separate resources for most of the subdevices so we cannot simply call
mfd_add_devices() to create all of them but instead we need to call it
separately for each device.
The new MFD driver continues to expose two sysfs attributes that allow
userspace to send IPC commands to the PMC/SCU to avoid breaking any
existing applications that may use these. Generally this is bad idea so
document this in the ABI documentation.

The current SCU IPC API has been operating on a single instance and
there has been no way to pin the providing module in place when the SCU
IPC is in use.
This implements a new API that takes the SCU IPC instance as first
parameter (NULL means the single instance is being used). The SCU IPC
instance can be retrieved by calling new function intel_scu_ipc_dev_get()
that take care of pinning the providing module in place as long as
intel_scu_ipc_dev_put() is not called.
The old API is updated to call the new API and is is left there in the
legacy API header to support the existing users that cannot be converted
easily.
Subsequent patches will convert most of the users over to the new API.

The SCU IPC functionality is usable outside of Intel MID devices. For
example modern Intel CPUs include the same thing but now it is called
PMC (Power Management Controller) instead of SCU. To make the IPC
available for those split the driver into core part (intel_scu_ipc.c)
and the SCU PCI driver part (intel_scu_pcidrv.c) which then calls the
former before it goes and creates rest of the SCU devices. The SCU IPC
will also register a new class that gets assigned to the device that is
created under the parent PCI device.
We also split the Kconfig symbols so that INTEL_SCU_IPC enables the SCU
IPC library and INTEL_SCU_PCI the SCU driver and convert the users
accordingly. While there remove default y from the INTEL_SCU_PCI symbol
as it is already selected by X86_INTEL_MID.
