fe5b6aaef7 Input: i8042 - fix refount leak on sparc 
In i8042_platform_init() and i8042_platform_exit(), we should call
of_node_put() for the reference 'root' returned by
of_find_node_by_path() which has increased the refcount.

Fixes: f57caaefac ("[SERIO] i8042-sparcio.h: Convert to of_driver framework.")

fdd7c96176 Input: i8042 - add LoongArch support in i8042-acpipnpio.h 
LoongArch uses ACPI and nearly the same as X86/IA64 for 8042. So modify
i8042-acpipnpio.h slightly and enable it for LoongArch in i8042.h. Then
i8042 driver can work well under the ACPI firmware with PNP typed key-
board and mouse configured in DSDT.

Now i8042-x86ia64io.h is shared by X86 and IA64, but it can be shared
by more platforms (such as LoongArch) with ACPI firmware on which PNP
typed keyboard and mouse is configured in DSDT. So rename it to i8042-
acpipnpio.h.

63c5eb157c Input: pinephone-keyboard - support the proxied I2C bus 
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.

882597aff2 Input: auo-pixcir-ts - drop support for platform data 
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).

d56111ed58 Input: iqs7222 - set all ULP entry masks by default 
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.
