The PinePhone keyboard case contains a battery managed by an integrated
power bank IC. The power bank IC communicates over I2C, and the keyboard
MCU firmware provides an interface to read and write its registers.
Let's use this interface to implement a SMBus adapter, so we can reuse
the driver for the power bank IC.

Both i.MX6 and i.MX8 reference manuals list 0xBF8 as SNVS_HPVIDR1
(chapters 57.9 and 6.4.5 respectively).
Without this, trying to read the revision number results in 0 on
all revisions, causing the i.MX6 quirk to apply on all platforms,
which in turn causes the driver to synthesise power button release
events instead of passing the real one as they happen even on
platforms like i.MX8 where that's not wanted.

Currently there are no users of auo_pixcir_ts_platdata in the mainline, and
having it (with legacy gpio numbers) prevents us from converting the driver
to gpiod API, so let's drop it.
If, in the future, someone wants to use this driver on non-device tree,
non-ACPI system, they should use static device properties instead of
platform data.

Noticed this while trying to debug some unrelated issues: this laptop has
the ability to use rmi4 but doesn't by default. So let's fix that.
Tested locally, including mouse buttons, on my ThinkPad P1 G3. This might
also enable the X1 Extreme G3, but I don't have such a system to test
locally (presumably Mark can chime in if that's the case).

Some devices expose an ultra-low-power (ULP) mode entry mask for
each channel. If the mask is set, the device cannot enter ULP so
long as the corresponding channel remains in an active state.
The vendor has advised setting the mask for any disabled channel.
To accommodate this suggestion, initially set all masks and then
clear them only if specified in the device tree.

An effort has been made to support every official model and firmware
version I could track down info on. The following controllers _should_
have working paddles with this PR:
- Xbox Elite (**untested**)
- Xbox Elite Series 2 on early firmwares (**untested**)
- Xbox Elite Series 2 on v4 firmwares (Tested v4.8.1908.0)
- Xbox Elite Series 2 on v5 pre-BLE firmwares (**untested**)
- Xbox Elite Series 2 on v5 post-BLE firmwares (Tested v5.13.3143.0)
This patch also introduces correct handling for the Elite 1 controller
and properly suppresses paddle inputs when using a custom profile slot.
Starting with firmware v5.11, certain inputs for the Elite 2 were moved
to an extra packet that is not enabled by default.
We must first manually enable this extra packet in order to correctly
process paddle input data with these later firmwares.

Suspending and resuming the system can sometimes cause the out
URB to get hung after a reset_resume. This causes LED setting
and force feedback to break on resume. To avoid this, just drop
the reset_resume callback so the USB core rebinds xpad to the
wireless pads on resume if a reset happened.
A nice side effect of this change is the LED ring on wireless

This change replaces the support for GPIs as key event generators.
Instead of reporting the events directly, we add a gpio based irqchip
so that these events can be consumed by keys defined in the gpio-keys
driver (as it's goal is indeed for keys on GPIOs capable of generating
interrupts). With this, the gpio-adp5588 driver can also be dropped.
The basic idea is that all the pins that are not being used as part of
the keymap matrix can be possibly requested as GPIOs by gpio-keys
(it's also fine to use these pins as plain interrupts though that's not
really the point).
Since the gpiochip now also has irqchip capabilities, we should only
remove it after we free the device interrupt (otherwise we could, in
theory, be handling GPIs interrupts while the gpiochip is concurrently
removed). Thus the call 'adp5588_gpio_add()' is moved and since the
setup phase also needs to come before making the gpios visible, we also
need to move 'adp5588_setup()'.
While at it, always select GPIOLIB so that we don't need to use #ifdef
guards.

The value returned by an i2c driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)
So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

MediaTek keypad has 2 modes of detecting key events:
- single key: each (row, column) can detect one key
- double key: each (row, column) is a group of 2 keys
Double key support exists to minimize cost, since it reduces the number
of pins required for physical keys.
Double key is configured by setting BIT(0) of the KP_SEL register.
Enable double key matrix support based on the mediatek,keys-per-group

implementation when running in compat mode, otherwise the signed int32
parameters min_nr and nr will be incorrectly handled as unsigned int64 values.
Other than that just small cleanups:
* hardware database housekeeping and proper /proc/iomem output
* add proper function exit code if probe functions fail
* drop stale variables (pa_swapper_pg_lock)
* drop unneccessary zero-initializations
* typo fixes in comments

Pull input fixes from Dmitry Torokhov:
- fix Goodix driver to properly behave on the Aya Neo Next
- some more sanity checks in usbtouchscreen driver
- a tweak in wm97xx driver in preparation for remove() to return void
- a clarification in input core regarding units of measurement for
resolution on touch events.
* tag 'input-for-v5.19-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
Input: document the units for resolution of size axes
Input: goodix - call acpi_device_fix_up_power() in some cases
Input: wm97xx - make .remove() obviously always return 0
Input: usbtouchscreen - add driver_info sanity check
On ACPI boards, when we cannot get the GPIOs to do a reset ourselves
if necessary, call acpi_device_fix_up_power() to force the ACPI _PS0
method to run.
On some devices without proper GPIO descriptions this will reset
the touchscreen for us and this may be necessary for us to be able
to communicate to the touchscreen at all.
Specifically on an Aya Neo Next this change will cause the _PS0()
ACPI function to call INIT() which does:
Method (INIT, 0, Serialized)
{
TP_I = 0x00A50000
TP_R = 0x00A50000
Sleep (0x0A)
TP_I = 0x00E50000
Sleep (One)
TP_R = 0x00E50000
Sleep (0x06)
TP_I = 0x00A50000
Sleep (0x3C)
TP_I = 0x00041800
}
On older kernels the ACPI core assumed a power-on was necessary by itself
and would run _PS0 before our probe function runs, which can be seen from
the GPIO pin ctrl registers in /sys/kernel/debug/gpio which match
the above hex values with older kernels.
With newer kernels before this change the GPIO pin ctrl registers do not
match, indicating INIT() has not run and probing the touchscreen fails.
This change makes Linux run _PS0() again fixing the touchscreen not working
on the Aya Neo Next.

The MediaTek keypad has a total of 6 input rows and 6 input columns.
By default, rows/columns 0-2 are enabled.
This is controlled by the KP_SEL register:
- bits[9:4] control row selection
- bits[15:10] control column selection
Each bit enables the corresponding row/column number (e.g KP_SEL[4]
enables ROW0)
Depending on how the keypad is wired, this may result in wrong readings
of the keypad state.
Program the KP_SEL register to limit the key detection to n_rows,
n_cols we retrieve from the device tree.

The MediaTek keypad has a set of bits representing keys,
from KEY0 to KEY77, arranged in 5 chunks of 15 bits split into 5 32-bit
registers.
In our implementation, we simply decided to use register number as row
and offset in the register as column when encoding our "matrix".
Because of this, we can have a 5x32 matrix which does not match the
hardware at all, which is confusing.
Change the row/column calculation to match the hardware.

The list is quite massive as neither the TUXEDO nor the Clevo dmi strings

Merge i8042 quirk tables to reduce code duplication for devices that need
more than one quirk. Before every quirk had its own table with devices
needing that quirk. If a new quirk needed to be added a new table had to
be created. When a device needed multiple quirks, it appeared in multiple
tables. Now only one table called i8042_dmi_quirk_table exists. In it every
device has one entry and required quirks are coded in the .driver_data
field of the struct dmi_system_id used by this table. Multiple quirks for
one device can be applied by bitwise-or of the new SERIO_QUIRK_* defines.
Also align quirkable options with command line parameters and make vendor
wide quirks per device overwriteable on a per device basis. The first match
is honored while following matches are ignored. So when a vendor wide quirk
is defined in the table, a device can inserted before and therefore
ignoring the vendor wide define.

Add a sanity check on the device id-table driver_info field to make sure
we never access a type structure (and function pointers) outside of the
device info array (e.g. if someone fails to ifdef a device-id entry).
Note that this also suppresses a compiler warning with -Warray-bounds
(gcc-11.3.0) when compile-testing the driver without enabling any of
the device type Kconfig options:
drivers/input/touchscreen/usbtouchscreen.c: In function 'usbtouch_probe':

If the device suffers a spurious reset during ATI, there is no point
in enduring any further retries. Instead, simply return successfully
from the polling loop.
In this case, the interrupt handler will intervene and recognize the
device has been reset. It then proceeds to initialize the device and
trigger ATI once more.
As part of this change, swap the order of status field evaluation to
match that of the interrupt handler, and correct a nearby off-by-one
error that causes an error message to suggest the final attempt will
be retried.

If the device suffers a spurious reset while reacting to a previous
spurious reset, the second reset interrupt is preempted because the
ACK_RESET bit is written last.
To solve this problem, write the ACK_RESET bit prior to writing any
other registers. This ensures that any registers written before the
second spurious reset will be rewritten.
Last but not least, the order in which the ACK_RESET bit is written
relative to the second filter beta register is important for select
variants of silicon. Enforce the correct order so as to not clobber
the system status register.

Select variants of silicon silently mirror part of the event mask
register to the system setup register (0xD0), and vice versa. For
the following sequence:
1. Read registers 0xD0 onward and store their contents.
2. Modify the contents, including event mask fields.
3. Write registers 0xD0 onward with the modified contents.
4. Write register 0xD0 on its own again later, using the contents
from step 1 to populate any reserved fields.
...the event mask register (e.g. address 0xDA) has been corrupted
by writing register 0xD0 with contents that were made stale after
step 3.
To solve this problem, read register 0xD0 once more between steps
3 and 4. When register 0xD0 is written during step 4, the portion
which is mirrored to the event mask register already matches what
was written in step 3.

The release cycle of any key mapped to a slider gesture relies upon
trailing interrupts generated by other unmasked sources, the timing
and presence of which are inconsistent.
To solve this problem, explicitly report a release cycle to emulate
a full keystroke. Also, unmask touch interrupts if the slider press
event is defined; this ensures the device reports a final interrupt
with coordinate = 0xFFFF once the finger is lifted.
As a result of how the logic has been refactored, the press/release
event can now be mapped to a GPIO. This is more convenient than the
previous solution, which required each channel within the slider to
specify the same GPIO.
As part of this change, use the device's resolution rather than its
number of interrupt status registers to more safely determine if it
is capable of reporting gestures.
Last but not least, make the code a bit simpler by eliminating some
unnecessarily complex conditional statements and a macro that could
be derived using information that is already available.

If a positive swipe/flick gesture is defined but the corresponding
negative gesture is not, the former is inadvertently disabled. Fix
this by gently refactoring the logic responsible for disabling all
gestures by default.
As part of this change, make the code a bit simpler by eliminating
a superfluous conditional check. If a slider event does not define
an enable control, the second term of the bitwise AND operation is
simply 0xFFFF.

This driver abuses the efivar API, by using a few of its helpers on
entries that were not instantiated by the API itself. This is a problem
as future cleanup work on efivars is complicated by this.
So let's just switch to the get/set variable runtime wrappers directly.

Here is the "big" set of USB and Thunderbolt driver changes for
5.18-rc1. For the most part it's been a quiet development cycle for the

Included in here are:
- Thunderbolt driver updates:
- fixes for devices without displayport adapters
- lane bonding support and improvements
- other minor changes based on device testing
- dwc3 gadget driver changes. It seems this driver will never
be finished given that the IP core is showing up in zillions
of new devices and each implementation decides to do something
different with it...
- uvc gadget driver updates as more devices start to use and
rely on this hardware as well
- usb_maxpacket() api changes to remove an unneeded and unused
parameter.
- usb-serial driver device id updates and small cleanups
- typec cleanups and fixes based on device testing
- device tree updates for usb properties
- lots of other small fixes and driver updates.
All of these have been in linux-next for weeks with no reported

PMICs in this driver, move the long press debounce mask to struct
mtk_pmic_regs and use that in mtk_pmic_keys_lp_reset_setup() instead
of directly using the definition.
While at it, remove the definition for MTK_PMIC_RST_DU_SHIFT as we
are able to calculate it dynamically and spares us some unnecessary
new definitions around for future per-PMIC variations of RST_DU_MASK.
Lastly, it was necessary to change the function signature of
mtk_pmic_keys_lp_reset_setup() to now pass a pointer to the main
mtk_pmic_regs structure, since that's where the reset debounce
mask now resides.

Sync up with mainline to get updates to OMAP4 keypad driver and other
upstream goodies.
Instead of a virtual kernel address use a pointer of the associated
struct page as second parameter of gnttab_end_foreign_access().
Most users have that pointer available already and are creating the
virtual address from it, risking problems in case the memory is
located in highmem.
gnttab_end_foreign_access() itself won't need to get the struct page
from the address again.

This series has been 12 years in the making, it mostly finishes the
work that was started with the founding of Linaro to clean up platform
support in the kernel.
The largest change here is a cleanup of the omap1 platform, which
is the final ARM machine type to get converted to the common-clk
subsystem. All the omap1 specific drivers are now made independent of the
mach/*.h headers to allow the platform to be part of a generic ARMv4/v5
multiplatform kernel. The last bit that enables this support is still
missing here while we wait for some last dependencies to make it into
the mainline kernel through other subsystems.
The s3c24xx, ixp4xx, iop32x, ep93xx and dove platforms were all almost
at the point of allowing multiplatform kernels, this work gets completed
here along with a few additional cleanup. At the same time, the s3c24xx
and s3c64xx are now deprecated and expected to get removed in the future.
The PXA and OMAP1 bits are in a separate branch because of dependencies.
Once both branches are merged, only the three Intel StrongARM platforms
(RiscPC, Footbridge/NetWinder and StrongARM1100) need separate kernels,
and there are no plans to include these.

Currently, when trying to suspend and resume with VirtualPS/2 VMMouse
there is an error message after resuming:
psmouse serio1: vmmouse: Unable to re-enable mouse when reconnecting, err: -6
and the mouse will no longer be operable, requiring full rescan to find a
another driver to use for the port.
This error is due to QEMU still generating PS2 events which the kernel is
not consuming until resume time, where they interfere with mouse
identification and ultimately resulting in an error getting
VMMOUSE_VERSION_ID.
Test scenario:
1) start virtual machine with qemu command "vmport=on"
2) click suspend botton to enter suspend mode
3) resume and observe the error message in the kernel logs
Let's fix this by disabling the vmmouse in its reset handler. This will
notify qemu to stop vmmouse and remove the handler.

If the device is a detachable (and therefore lacks full keyboard), we may
still want to load this driver because the device might have some other
buttons or switches (e.g. volume and power buttons or a tablet mode
switch). In such case we do not want to register the "main" keyboard device
to allow userspace detect when the detachable keyboard is disconnected and
adjust the system behavior for the tablet mode.
Originally it was suggested to simply skip keyboard registration if row and
columns properties didn't exist, but that approach did not convey the
intent strongly enough and also had a slight problem for migrating existing
DTBs without updating the kernel first, so it was decided to introduce new
google,cros-ec-keyb-switches to explicitly mark devices that only have
axillary buttons and switches.

- minor fixes to omap4-keypad and cypress-sf drivers
* tag 'input-for-v5.18-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:

The third argument of usb_maxpacket(): in_out has been deprecated
because it could be derived from the second argument (e.g. using
usb_pipeout(pipe)).
N.B. function usb_maxpacket() was made variadic to accommodate the
transition from the old prototype with three arguments to the new one
with only two arguments (so that no renaming is needed). The variadic
argument is to be removed once all users of usb_maxpacket() get
migrated.

The omap-keypad driver currently relies on including mach/memory.h
implicitly, but that won't happen once omap1 is converted to
CONFIG_ARCH_MULTIPLATFORM. Include the required header
explicitly.

Variable ret is being assigned a value that is never read, it is
being re-assigned again in either path of the if statement. The
assignment is redundant and can be removed.
Cleans up clang scan build warning:
Although the value stored to 'ret' is used in the enclosing expression,
the value is never actually read from 'ret' [deadcode.DeadStores]

The mach/hardware.h is included in lots of places, and it provides
three different things on pxa:
- the cpu_is_pxa* macros
- an indirect inclusion of mach/addr-map.h
- the __REG() and io_pv2() helper macros
Split it up into separate <linux/soc/pxa/cpu.h> and mach/pxa-regs.h
headers, then change all the files that use mach/hardware.h to
include the exact set of those three headers that they actually
need, allowing for further more targeted cleanup.
linux/soc/pxa/cpu.h can remain permanently exported and is now in
a global location along with similar headers. pxa-regs.h and
addr-map.h are only used in a very small number of drivers now
and can be moved to arch/arm/mach-pxa/ directly when those drivers
are to pass the necessary data as resources.

Select callers of iqs7222_parse_props() do not expect a child node
to be derived and returned via pointer. As such, these callers set
**child_node to NULL. However, this pointer is dereferenced in all
cases.
To solve this problem, dereference the pointer only for cases that
expect a child node in the first place. In these cases, the caller
provides a valid pointer.

If fwnode_property_count_u32() returns a negative error code then,
because of type promotion, the "count > ARRAY_SIZE(pins)" condition
will be true. The negative "count" is type promoted to a high unsigned
size_t value.
That means the "else if (count < 0)" condition will always be false and
we don't print that error message or propagate the error code from
fwnode_property_count_u32() as intended.
Fix this by re-ordering the checks so that we check for negative first.

The mmio base address is used for the only purpose of initializing
regmap for this driver, hence it's not necessary to have it in the
main driver structure, as it is used only in the probe() callback.
Move it local to function mt6779_keypad_pdrv_probe().
This commit brings no functional changes.

This reverts commit 37ef4c19b4.
The touchpad present in the Dell Precision 7550 and 7750 laptops
reports a HID_DG_BUTTONTYPE of type MT_BUTTONTYPE_CLICKPAD. However,
the device is not a clickpad, it is a touchpad with physical buttons.
In order to fix this issue, a quirk for the device was introduced in
libinput [1] [2] to disable the INPUT_PROP_BUTTONPAD property:
[Precision 7x50 Touchpad]
MatchBus=i2c
MatchUdevType=touchpad
MatchDMIModalias=dmi:*svnDellInc.:pnPrecision7?50*
AttrInputPropDisable=INPUT_PROP_BUTTONPAD
However, because of the change introduced in 37ef4c19b4 ("Input: clear
BTN_RIGHT/MIDDLE on buttonpads") the BTN_RIGHT key bit is not mapped
anymore breaking the device right click button and making impossible to
workaround it in user space.
In order to avoid breakage on other present or future devices, revert
the patch causing the issue.

The overwhelming bulk of this pull request is a change from Uwe
Kleine-König which changes the return type of the remove() function to
void as part of some wider work he's doing to do this for all bus types,
causing updates to most SPI device drivers. The branch with that on has
been cross merged with a couple of other trees which added new SPI
drivers this cycle, I'm not expecting any build issues resulting from
the change.
Otherwise it's been a relatively quiet release with some new device
support, a few minor features and the welcome completion of the
conversion of the subsystem to use GPIO descriptors rather than numbers:
- Change return type of remove() to void.
- Completion of the conversion of SPI controller drivers to use GPIO
descriptors rather than numbers.
- Quite a few DT schema conversions.
- Support for multiple SPI devices on a bus in ACPI systems.
- Big overhaul of the PXA2xx SPI driver.
- Support for AMD AMDI0062, Intel Raptor Lake, Mediatek MT7986 and
MT8186, nVidia Tegra210 and Tegra234, Renesas RZ/V2L, Tesla FSD and

Add support for the IST3038C touchscreen IC from Imagis, based on
downstream driver. The driver supports multi-touch (10 touch points)
The IST3038C IC supports touch keys, but the support isn't added
because the touch screen used for testing doesn't utilize touch keys.
Looking at the downstream driver, it is possible to add support
for other Imagis ICs of IST30**C series.

media Kconfig has two entries associated to V4L API:
VIDEO_DEV and VIDEO_V4L2.
On Kernel 2.6.x, there were two V4L APIs, each one with its own flag.
VIDEO_DEV were meant to:
1) enable Video4Linux and make its Kconfig options to appear;
2) it makes the Kernel build the V4L core.
while VIDEO_V4L2 where used to distinguish between drivers that
implement the newer API and drivers that implemented the former one.
With time, such meaning changed, specially after the removal of
all V4L version 1 drivers.
At the current implementation, VIDEO_DEV only does (1): it enables
the media options related to V4L, that now has:
menu "Video4Linux options"
visible if VIDEO_DEV
source "drivers/media/v4l2-core/Kconfig"
endmenu
but it doesn't affect anymore the V4L core drivers.
The rationale is that the V4L2 core has a "soft" dependency
at the I2C bus, and now requires to select a number of other
Kconfig options:
config VIDEO_V4L2
tristate
depends on (I2C || I2C=n) && VIDEO_DEV
select RATIONAL
select VIDEOBUF2_V4L2 if VIDEOBUF2_CORE
default (I2C || I2C=n) && VIDEO_DEV
In the past, merging them would be tricky, but it seems that it is now
possible to merge those symbols, in order to simplify V4L dependencies.
Let's keep VIDEO_DEV, as this one is used on some make *defconfig
configurations.

I observed the following problem with the BT404 touch pad
running the Phosh UI:
When e.g. typing on the virtual keyboard pressing "g" would
produce "ggg".
After some analysis it turns out the firmware reports that three
fingers hit that coordinate at the same time, finger 0, 2 and
4 (of the five available 0,1,2,3,4).
DOWN
Zinitix-TS 3-0020: finger 0 down (246, 395)
Zinitix-TS 3-0020: finger 1 up (0, 0)
Zinitix-TS 3-0020: finger 2 down (246, 395)
Zinitix-TS 3-0020: finger 3 up (0, 0)
Zinitix-TS 3-0020: finger 4 down (246, 395)
UP
Zinitix-TS 3-0020: finger 0 up (246, 395)
Zinitix-TS 3-0020: finger 2 up (246, 395)
Zinitix-TS 3-0020: finger 4 up (246, 395)
This is one touch and release: i.e. this is all reported on
touch (down) and release.
There is a field in the struct touch_event called finger_cnt
which is actually a bitmask of the fingers active in the
event.
Rename this field finger_mask as this matches the use contents
better, then use for_each_set_bit() to iterate over just the
fingers that are actally active.
Factor out a finger reporting function zinitix_report_fingers()
to handle all fingers.
Also be more careful in reporting finger down/up: we were
reporting every event with input_mt_report_slot_state(..., true);
but this should only be reported on finger down or move,
not on finger up, so also add code to check p->sub_status
to see what is happening and report correctly.
After this my Zinitix BT404 touchscreen report fingers
flawlessly.
The vendor drive I have notably does not use the "finger_cnt"
and contains obviously incorrect code like this:
if (touch_dev->touch_info.finger_cnt > MAX_SUPPORTED_FINGER_NUM)
touch_dev->touch_info.finger_cnt = MAX_SUPPORTED_FINGER_NUM;
As MAX_SUPPORTED_FINGER_NUM is an ordinal and the field is
a bitmask this seems quite confused.

The drivers/platform/surface/surface3_button.c code is alsmost a 1:1 copy
of the soc_button_array code.
The only big difference is that it binds to an i2c_client rather then to
a platform_device. The cause of this is the ACPI resources for the MSHW0028
device containing a bogus I2cSerialBusV2 resource which causes the kernel
to instantiate an i2c_client for it instead of a platform_device.
Add "MSHW0028" to the ignore_serial_bus_ids[] list in drivers/apci/scan.c,
so that a platform_device will be instantiated and add support for
the MSHW0028 HID to soc_button_array.
This fully replaces surface3_button, which will be removed in a separate
commit (since it binds to the now no longer created i2c_client it no
longer does anyyhing after this commit).
Note the MSHW0028 id is used by Microsoft to describe the tablet buttons on
both the Surface 3 and the Surface 3 Pro and the actual API/implementation
for the Surface 3 Pro is quite different. The changes in this commit should
not impact the separate surfacepro3_button driver:
1. Because of the bogus I2cSerialBusV2 resource problem that driver binds
to the acpi_device itself, so instantiating a platform_device instead of
an i2c_client does not matter.
2. The soc_button_array driver will not bind to the MSHW0028 device on
the Surface 3 Pro, because it has no GPIO resources.

Before these changes elan_suspend() would only disable the regulator
when device_may_wakeup() returns false; whereas elan_resume() would
unconditionally enable it, leading to an enable count imbalance when
device_may_wakeup() returns true.
This triggers the "WARN_ON(regulator->enable_count)" in regulator_put()
when the elan_i2c driver gets unbound, this happens e.g. with the
hot-plugable dock with Elan I2C touchpad for the Asus TF103C 2-in-1.
Fix this by making the regulator_enable() call also be conditional
on device_may_wakeup() returning false.

Because there is no way to detect if the touchscreen has pen support,
the driver is allocating and registering the input_pen input_dev on
receiving the first pen event.
But this means that the input_dev gets allocated after the request_irq()
call which means that the devm framework will free it before disabling
the irq, leaving a window where the irq handler may run and reference the
free-ed input_dev.
To fix this move the allocation of the input_pen input_dev to before
the request_irq() call, while still only registering it on the first pen
event so that the driver does not advertise pen capability on touchscreens
without it (most goodix touchscreens do not have pen support).

The input core's error handling for input_alloc_absinfo() failures
is based on ignoring the error until input_register_device() runs
and then checks for the failure like this:
if (test_bit(EV_ABS, dev->evbit) && !dev->absinfo) {
dev_err(&dev->dev, ...);
return -EINVAL;
}
This relies on EV_ABS actually getting set in dev->evbit even
if input_alloc_absinfo() fails, change input_set_abs_params() and
input_set_capability() to actually adhere to this.

ACPI/x86 devices with a Cherry Trail SoC should have a GpioInt + a regular
GPIO ACPI resource in their ACPI tables.
Some CHT devices have a bug, where the also is bogus interrupt resource
(likely copied from a previous Bay Trail based generation of the device).
The i2c-core-acpi code will assign the bogus, non-working, interrupt
resource to client->irq. Add a workaround to fix this up.

Merge tag 'v5.17-rc4' into next
Sync up with mainline to get the latest changes in HID subsystem.
When we switch from emulated PS/2 to native (RMI4 or Elan) protocols, we
create SMBus companion devices that are attached to I2C/SMBus controllers.
However, when suspending and resuming, we also need to make sure that we
take into account the PS/2 device they are associated with, so that PS/2
device is suspended after the companion and resumed before it, otherwise
companions will not work properly. Before I2C devices were marked for
asynchronous suspend/resume, this ordering happened naturally, but now we
need to enforce it by establishing device links, with PS/2 devices being
suppliers and SMBus companions being consumers.
Fixes: 172d931910 ("i2c: enable async suspend/resume on i2c client devices")

The PS/2 bus defines the data and clock line be open drain, therefore
for both enforce the particular GPIO flags in the driver.
Without enforcing to flag at least the clock gpio as open drain we run
into the following warning:
WARNING: CPU: 1 PID: 40 at drivers/gpio/gpiolib.c:3175 gpiochip_enable_irq+0x54/0x90
gpiochip_enable_irq() warns on a GPIO being configured as output while
serving as IRQ source without being flagged as open drain.

Sending the data before processing the stop bit from the device already
saves the data of the current xfer in case the stop bit is missed.
However, when TX xfers are enabled this introduces a race condition when
a peripheral driver using the bus immediately requests a TX xfer from IRQ
context.
Therefore the data must be send after receiving the stop bit, although
it is possible the data is lost when missing the stop bit.

Actually, there's no extra clock pulse to wait for.
The assumption of an extra clock pulse was mistakenly derived from the
fact that by the time this driver was introduced the GPIO controller of
the test machine (bcm2835) generated spurious interrupts.
Since now spurious interrupts are handled properly this can and must be
removed in order to make TX xfers work properly.
While at it, remove duplicate gpiod_direction_input(). The data gpio
must already be configured to act as input when receiving the ACK bit.
This patch is tested with the original hardware (peripherals and board)
the driver was developed on.

Using jiffies for the IRQ timekeeping is not sufficient for two reasons:
(1) Usually jiffies have a resolution of 1ms to 10ms. The IRQ intervals
based on the clock frequency of PS2 protocol specification (10kHz -
16.7kHz) are between ~60us and 100us only. Therefore only those IRQ
intervals can be detected which are either at the end of a transfer
or are overly delayed. While this is sufficient in most cases, since
we have quite a lot of ways to detect faulty transfers, it can
produce false positives in rare cases: When the jiffies value
changes right between two interrupt that are in time, we wrongly
assume that we missed one or more clock cycles.
(2) Some gpio controllers (e.g. the one in the bcm283x chips) may generate
spurious IRQs when processing interrupts in the frequency given by PS2
devices.
Both issues can be fixed by using ktime resolution for IRQ timekeeping.
However, it is still possible to miss clock cycles without detecting
them. When the PS2 device generates the falling edge of the clock signal
we have between ~30us and 50us to sample the data line, because after
this time we reach the next rising edge at which the device changes the
data signal already. But, the only thing we can detect is whether the
IRQ interval is within the given period. Therefore it is possible to
have an IRQ latency greater than ~30us to 50us, sample the wrong bit on
the data line and still be on time with the next IRQ. However, this can
only happen when within a given transfer the IRQ latency increases
slowly.

The value returned by an spi driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)
So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

Buttonpads are expected to map the INPUT_PROP_BUTTONPAD property bit
and the BTN_LEFT key bit.
As explained in the specification, where a device has a button type
value of 0 (click-pad) or 1 (pressure-pad) there should not be
discrete buttons:
https://docs.microsoft.com/en-us/windows-hardware/design/component-guidelines/touchpad-windows-precision-touchpad-collection#device-capabilities-feature-report
However, some drivers map the BTN_RIGHT and/or BTN_MIDDLE key bits even
though the device is a buttonpad and therefore does not have those
buttons.
This behavior has forced userspace applications like libinput to
implement different workarounds and quirks to detect buttonpads and
offer to the user the right set of features and configuration options.
For more information:
https://gitlab.freedesktop.org/libinput/libinput/-/merge_requests/726
In order to avoid this issue clear the BTN_RIGHT and BTN_MIDDLE key
bits when the input device is register if the INPUT_PROP_BUTTONPAD
property bit is set.
Notice that this change will not affect udev because it does not check
for buttons. See systemd/src/udev/udev-builtin-input_id.c.

Some pmics of the mt6397 family (such as MT6358), have two IRQs per
physical key: one for press event, another for release event.
The mtk-pmic-keys driver assumes that each key only has one
IRQ. The key index and the RES_IRQ resource index have a 1/1 mapping.
This won't work for MT6358, as we have multiple resources (2) for one key.
To prepare mtk-pmic-keys to support MT6358, retrieve IRQs by name
instead of by index.
