d90be6e4aa Driver core changes for 6.10-rc1
Here is the small set of driver core and kernfs changes for 6.10-rc1.
 
 Nothing major here at all, just a small set of changes for some driver
 core apis, and minor fixups.  Included in here are:
   - sysfs_bin_attr_simple_read() helper added and used
   - device_show_string() helper added and used
 All usages of these were acked by the various maintainers.  Also in here
 are:
   - kernfs minor cleanup
   - removed unused functions
   - typo fix in documentation
   - pay attention to sysfs_create_link() failures in module.c finally.
 
 All of these have been in linux-next for a very long time with no
 reported problems.

62a12816cb ACPI fixes for 6.10-rc1
These make the ACPI EC driver always install the EC address space handler
 at the root of the ACPI namespace which causes it to take care of all EC
 operation regions everywhere, so in particular the custom EC address
 space handler in the WMI driver is not needed any more and accordingly
 it gets removed altogether.

Pull pci updates from Bjorn Helgaas:
 "Enumeration:

   - Skip E820 checks for MCFG ECAM regions for new (2016+) machines,
     since there's no requirement to describe them in E820 and some

     was masked incorrectly (Rick Wertenbroek)

  Synopsys DesignWare PCIe controller driver:

   - Restructure DBI register access to accommodate devices where this
     requires Refclk to be active (Manivannan Sadhasivam)

   - Remove the deinit() callback, which was only need by the
     pcie-rcar-gen4, and do it directly in that driver (Manivannan
     Sadhasivam)

   - Add dw_pcie_ep_cleanup() so drivers that support PERST# can clean
     up things like eDMA (Manivannan Sadhasivam)

   - Rename dw_pcie_ep_exit() to dw_pcie_ep_deinit() to make it parallel
     to dw_pcie_ep_init() (Manivannan Sadhasivam)

   - Rename dw_pcie_ep_init_complete() to dw_pcie_ep_init_registers() to
     reflect the actual functionality (Manivannan Sadhasivam)

   - Call dw_pcie_ep_init_registers() directly from all the glue
     drivers, not just those that require active Refclk from the host
     (Manivannan Sadhasivam)

   - Remove the "core_init_notifier" flag, which was an obscure way for
     glue drivers to indicate that they depend on Refclk from the host
     (Manivannan Sadhasivam)

   - Add DT binding J784S4 SoC Device ID (Siddharth Vadapalli)

   - Add DT binding J722S SoC support (Siddharth Vadapalli)

   cleanup/consolidation/maintainability work in the series "mm/treewide:
   Remove pXd_huge() API".
 
 - In the series "Allow migrate on protnone reference with
   MPOL_PREFERRED_MANY policy", Donet Tom has optimized mempolicy's
   MPOL_PREFERRED_MANY mode, yielding almost doubled performance in one
   test.
 
 - In their series "Memory allocation profiling" Kent Overstreet and
   Suren Baghdasaryan have contributed a means of determining (via
   /proc/allocinfo) whereabouts in the kernel memory is being allocated:
   number of calls and amount of memory.
 
 - Matthew Wilcox has provided the series "Various significant MM
   patches" which does a number of rather unrelated things, but in largely
   similar code sites.
 
 - In his series "mm: page_alloc: freelist migratetype hygiene" Johannes
   Weiner has fixed the page allocator's handling of migratetype requests,
   with resulting improvements in compaction efficiency.
 
 - In the series "make the hugetlb migration strategy consistent" Baolin
   Wang has fixed a hugetlb migration issue, which should improve hugetlb
   allocation reliability.
 
 - Liu Shixin has hit an I/O meltdown caused by readahead in a
   memory-tight memcg.  Addressed in the series "Fix I/O high when memory
   almost met memcg limit".

98a83da39b platform/x86: wmi: Remove custom EC address space handler
The custom EC address space handler in the WMI driver was only needed
because the EC driver did not install its address space handler for
EC operation regions beyond the EC device scope in the ACPI namespace.

That has just changed, so the custom EC address handler is not needed
any more and it can be removed.

2513563edc platform/x86: Add new MeeGoPad ANX7428 Type-C Cross Switch driver
Some MeeGoPad top-set boxes have an ANX7428 Type-C Switch for USB3.1 Gen 1
and DisplayPort over Type-C alternate mode support.

The ANX7428 has a microcontroller which takes care of the PD negotiation
and automatically sets the builtin Crosspoint Switch to send the right
signal to the 4 highspeed pairs of the Type-C connector. It also takes
care of HPD and AUX channel routing for DP alternate mode.

IOW the ANX7428 operates fully autonomous and to the x5-Z8350 SoC
things look like there simple is a USB-3 Type-A connector and a
separate DisplayPort connector. Except that the BIOS does not
power on the ANX7428 at boot (meh).

Add a driver to power on the ANX7428. This driver is added under
drivers/platform/x86 rather than under drivers/usb/typec for 2 reasons:

1. This driver is specifically written to work with how the ANX7428 is
described in the ACPI tables of the MeeGoPad x86 (Cherry Trail) devices.

2. This driver only powers on the ANX7428 and does not do anything wrt
its Type-C functionality. It should be possible to tell the controller
which data- and/or power-role to negotiate and to swap the role(s) after
negotiation but the MeeGoPad top-set boxes always draw their power from
a separate power-connector and they only support USB host-mode. So this
functionality is unnecessary and due to lack of documentation this is
tricky to support.

484bae9e4d platform/x86: Add new Dell UART backlight driver
Dell All In One (AIO) models released after 2017 use a backlight controller
board connected to an UART.

In DSDT this uart port will be defined as:

   Name (_HID, "DELL0501")
   Name (_CID, EisaId ("PNP0501")

Instead of having a separate ACPI device with an UartSerialBusV2() resource
to model the backlight-controller, which would be the standard way to do
this.

The acpi_quirk_skip_serdev_enumeration() has special handling for this
and it will make the serial port code create a serdev controller device
for the UART instead of a /dev/ttyS0 char-dev. It will also create
a dell-uart-backlight driver platform device for this driver to bind too.

This new kernel module contains 2 drivers for this:

1. A simple platform driver which creates the actual serdev device
   (with the serdev controller device as parent)

2. A serdev driver for the created serdev device which exports
   the backlight functionality uses a standard backlight class device.

9426adb032 platform/x86: x86-android-tablets: Create LED device for Xiaomi Pad 2 bottom bezel touch buttons
The Xiaomi [Mi]Pad 2 has 3 menu / home / back capacitive touch-buttons
on its bottom bezel. These are backlit by LEDs attached to a TPS61158 LED
controller which is controlled by the "pwm_soc_lpss_2" PWM output.

Create a LED class device for this, using the new input-events trigger
as default trigger so that the buttons automatically light up on any
input activity.

Note alternatively a "leds_pwm" platform device could be created together
with the necessary fwnode_s_ and a fwnode link to the PWM controller.
There are 2 downsides to this approach:

1. The code would still need to pwm_get() the PWM controller to get/attach
a fwnode for the PWM controller fwnode link and setting up the necessary
fwnodes is non-trivial. So this would likely require more code then simply
registering the LED class device directly.

2. Currently the leds_pwm driver and its devicetree bindings do not support
limiting the maximum dutycycle to less then 100% which is required in this
case (the leds_pwm driver can probably be extended to allow this).

- Add a check for IORESOURCE_UNSET in p2sb_valid_resource() to catch

2fbe479c00 platform/chrome: cros_ec: Handle events during suspend after resume completion
Commit 47ea0ddb1f ("platform/chrome: cros_ec_lpc: Separate host
command and irq disable") re-ordered the resume sequence. Before that
change, cros_ec resume sequence is:
1) Enable IRQ
2) Send resume event
3) Handle events during suspend

After commit 47ea0ddb1f ("platform/chrome: cros_ec_lpc: Separate host
command and irq disable"), cros_ec resume sequence is:
1) Enable IRQ
2) Handle events during suspend
3) Send resume event.

This re-ordering leads to delayed handling of any events queued between
items 2) and 3) with the updated sequence. Also in certain platforms, EC
skips triggering interrupt for certain events eg. mkbp events until the
resume event is received. Such events are stuck in the host event queue
indefinitely. This change puts back the original order to avoid any
delay in handling the pending events.

9d1d36268f platform/x86: ISST: Support partitioned systems
A partitioned system has two different PCI VSEC devices per package.
A non-partitioned device has only one PCI VSEC device per package.
The current implementation only supports non partitioned systems.

Each partition maps a set of power domains. Other than reading from
different MMIO regions, there is no change in the SST functionality.
The scope of SST control is still per power domain. Hence user space
does not need to be aware of existence of partitions.

With partitions, existing per package information defined using struct
tpmi_sst_struct is enhanced to store information for both partitions. A
mapping function map_partition_power_domain_id() is introduced, which
maps to correct partition and index. This mapping function is called
in get_instance() and isst_if_clos_assoc(), before indexing into
tpmi_sst_struct->power_domain_info[].

The TPMI core platform info provides partition id and compute die ID
mask for each partition. Use this information to order power domains,
so that compute dies are presented before IO dies to match hardware
defined compute die ID for each CPU.

Add a new driver for the MSI WMI Platform interface. The underlying
ACPI WMI interface supports many features, but so far only reading
of fan speed sensors is implemented.

The driver was reverse-engineered based on a user request to the
lm-sensors project, see the github issue for details.

The ACPI WMI interface used by this driver seems to use the same
embedded controller interface as the msi-ec driver, but supports
automatic discovery of supported machines without relying on a
DMI whitelist.

The driver was tested by the user who created the github issue.

7545dc754b platform/x86: thinkpad_acpi: Add mappings for adaptive kbd clipping-tool and cloud keys
The X1 carbon 2014 / 2nd gen's adaptive keyboard top row's "Home" mode,
which is 1 of the 2 modes Linux supports, has clipping-tool and cloud
buttons which so far are not mapped.

I assume these were left as KEY_RESERVED because no suitable KEY_FOO codes
were available when support was added.

In the mean time we have gotten KEY_SELECTIVE_SCREENSHOT and this has been
used for the clipping-tool function under Fn + PrtSc on more traditional
ThinkPad keyboards already.

Finding a KEY_FOO code for the cloud key is harder looking at the symbol
it seems to refer to cloud-storage which made me think of file syncing,
or file transfer which has let me to pick KEY_XFER for this.

Note this is based on looking at a picture of the adaptive top row
in Home mode and has not been tested on an actual adaptive keyboard.

31456ffa7b platform/x86: thinkpad_acpi: Use correct keycodes for volume and brightness keys
Change the default keymap to report the correct keycodes for the volume and
brightness keys. Reporting key events for these is already filtered out by
the hotkey_reserved_mask which masks these keys out of hotkey_user_mask at
initialization time, so there is no need to also map them to KEY_RESERVED.

This avoids users, who want these to be reported, having to also remap
the keycodes on top of overriding hotkey_user_mask to report these
and Linux userspace has already been overriding the KEY_RESERVED mappings
with the correct keycodes through udev/hwdb/60-keyboard.hwdb for years now.

Also drop hotkey_unmap() it was only used to dynamically map the brightness
keys to KEY_RESERVED and after removing that it has no remaining users.

d3272c7445 platform/x86: thinkpad_acpi: Change hotkey_reserved_mask initialization
Change the hotkey_reserved_mask initialization to hardcode the list

iterate over the keymap will be removed when moving to sparse-keymaps.

Note only the 32 original hotkeys are affected by the hotkey_*_mask values:

	if (i < sizeof(hotkey_reserved_mask)*8)
		hotkey_reserved_mask |= 1 << i;

The (i < sizeof(hotkey_reserved_mask)*8) condition translates to (i < 32)
so this code only ever set bits in hotkey_reserved_mask for the 32 original
hotkeys. Therefor this patch does not set any bits in hotkey_reserved_mask
for the KEY_RESERVED mappings for the adaptive keyboard scancodes.

8f02154012 platform/x86: thinkpad_acpi: Do not send ACPI netlink events for unknown hotkeys
Do not send ACPI netlink events for unknown hotkeys, to avoid userspace
starting to rely on them. Instead these should be added to the keymap to
send evdev events.

This should not cause a behavior change for existing laptop models since
all currently known 0x1xxx events have a mapping.

In hindsight the ACPI netlink events should have been suppressed for
the adaptive keyboard and extended hotkeys events too. But the kernel has
been sending ACPI netlink events for those for a long time now, so we
cannot just stop sending them without potentially causing issues for
existing users who may depend on these.
