4ef4636707 Input: xpad - fix Share button on Xbox One controllers 
The Share button, if present, is always one of two offsets from the end of the
file, depending on the presence of a specific interface. As we lack parsing for
the identify packet we can't automatically determine the presence of that
interface, but we can hardcode which of these offsets is correct for a given
controller.

More controllers are probably fixable by adding the MAP_SHARE_BUTTON in the
future, but for now I only added the ones that I have the ability to test
directly.

11cdb506d0 Input: mtk-pmic-keys - fix possible null pointer dereference 
In mtk_pmic_keys_probe, the regs parameter is only set if the button is
parsed in the device tree. However, on hardware where the button is left
floating, that node will most likely be removed not to enable that
input. In that case the code will try to dereference a null pointer.

Let's use the regs struct instead as it is defined for all supported
platforms. Note that it is ok setting the key reg even if that latter is
disabled as the interrupt won't be enabled anyway.

9a046c1d21 Input: stmpe-ts - use module alias instead of device table 
When compile tested with W=1 on x86_64 with driver as built-in:

  stmpe-ts.c:371:34: error: unused variable 'stmpe_ts_ids' [-Werror,-Wunused-const-variable]

Ideally this would be referenced from the platform_driver, but since
the compatible string is already matched by the mfd driver for its
parent device, that would break probing.

In this case, the of_device_id table just serves as a module alias
for loading the driver, while the device itself is probed using
the platform device name.

Remove the table and instead use a module alias that reflects how
the driver is actually probed.

The current implementation of the goodix_berlin driver lacks support for
revisions A and B of the Berlin IC. This change adds support for the
gt9897 IC, which is a Berlin-A revision part.

The differences between revision D and A are rather minor, a handful of
address changes and a slightly larger read buffer. They were taken from
the driver published by Goodix, which does a few more things that don't
appear to be necessary for the touchscreen to work properly.

a2add51331 Input: iqs7222 - preserve system status register 
Some register groups reserve a byte at the end of their continuous
address space. Depending on the variant of silicon, this field may
share the same memory space as the lower byte of the system status
register (0x10).

In these cases, caching the reserved byte and writing it later may
effectively reset the device depending on what happened in between
the read and write operations.

Solve this problem by avoiding any access to this last byte within
offending register groups. This method replaces a workaround which
attempted to write the reserved byte with up-to-date contents, but
left a small window in which updates by the device could have been
clobbered.

Now that the driver does not touch these reserved bytes, the order
in which the device's registers are written no longer matters, and
they can be written in their natural order. The new method is also
much more generic, and can be more easily extended to new variants
of silicon with different register maps.

As part of this change, the register read and write functions must
be gently updated to support byte access instead of word access.

resume or boot which can be fixed with the SERIO_QUIRK_FORCENORESTORE
quirk.

The PB71RD keyboard is sometimes laggy after resume and the PC70DR, PB51RF,
P640RE, and PCX0DX_GN20 keyboard is sometimes unresponsive after resume.
This quirk fixes that.

729d163232 Input: i8042 - swap old quirk combination with new quirk for NHxxRZQ 
Some older Clevo barebones have problems like no or laggy keyboard after
resume or boot which can be fixed with the SERIO_QUIRK_FORCENORESTORE
quirk.

With the old i8042 quirks this devices keyboard is sometimes laggy after
resume. With the new quirk this issue doesn't happen.

90a0a63451 Input: matrix_keypad - add settle time after enabling all columns 
Matrix keypads with high capacity need a longer settle time after
enabling all columns before re-enabling interrupts. The delay gives
the system time to settle and avoids spurious interrupts.

Add a new optional device property to configure the delay after
enabling all columns. The default is no delay.
