 - a fix for xpad driver to properly support some third-party
   controllers that need a magic packet to start properly

 - a fix for psmouse driver to more reliably switch to RMI4 mode on
   devices that use native RMI4/SMbus protocol

 - a quirk for i8042 for TUXEDO Gemini 17 Gen1/Clevo PD70PN laptops

   newer APIs such as dev_err_probe(), devm_regulator_get_enable(), and
   others.

Merge branch 'next' into for-linus

2023-08-30T23:06:38+00:00

Prepare input updates for 6.6 merge window.

Input: goodix - add support for ACPI ID GDX9110

2023-08-15T18:38:50+00:00

The Goodix touchscreen controller with ACPI ID GDX9110 was not recognized
by the goodix driver. This patch adds this ID to the list of supported IDs,
allowing the driver to be used with this device. The change will allow
Linux to be used on ~1 million tablet devices used in Kenyan primary
schools.

Input: mms114 - add support for touch keys

2023-07-19T06:21:23+00:00

MELFAS MMS114 and similar touchscreens have support for touch keys.
Enable support of them in the driver. The keycodes to emit can be
controlled by the linux,keycodes DT property.

Sidenote - the MAX_TOUCHKEYS value is set to 15, as that's the
maximum value that the ID field can contain. I don't have access
to any datasheets that could confirm or deny whether this is accurate.

Most downstream drivers I've been able to find only use up to 2 keys
(though I did find a driver that mentioned up to 4, but only 2 were
used). They don't have any checks for a maximum keycode value, it is
just extracted from the ID bits (0xf mask).

The drivers I've been able to find also don't use touch ID 0; I assume
that it is never used, so the keycodes provided in the DT start from
touch ID 1. I suppose this is in-line with the regular behavior
for touch IDs in touchscreen events, as there the provided touch ID
is always lowered by 1, which would cause an overflow if it was 0...
Just in case, we quietly return if the touch ID is set to 0 here.

The implementation of the linux,keycodes property handling code was
adapted from the msg2638 driver.

Input: Explicitly include correct DT includes

2023-07-17T17:03:07+00:00

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

Merge tag 'v6.4' into next

2023-07-17T16:20:46+00:00

Sync up with mainline to bring in updates to shared infrastructure.

Input: iqs7211 - point to match data directly

2023-07-13T19:02:01+00:00

Point the OF match table directly to the struct that describes the
device as opposed to an intermediate enum; doing so simplifies the
code and avoids a clang warning.

As part of this change, the I2C device ID table is removed, as the
device cannot probe without an OF node due to the unique nature of
the hardware's interrupt pin.

Input: novatek-nvt-ts - add touchscreen model number to description

2023-07-10T18:50:38+00:00

A phoronix forum member actual found documentation on what the model
number for the touchscreen controller on the Acer Iconia One 7 B1-750 is.

Update the driver's description to include this.
