Pull input updates from Dmitry Torokhov:

 - a change to input core to trim amount of keys data in modalias string
   in case when a device declares too many keys and they do not fit in
   uevent buffer instead of reporting an error which results in uevent
   not being generated at all

 - support for Machenike G5 Pro Controller added to xpad driver

 - support for FocalTech FT5452 and FT8719 added to edt-ft5x06

 - support for new SPMI vibrator added to pm8xxx-vibrator driver

 - missing locking added to cyapa touchpad driver

 - removal of unused fields in various driver structures

 - explicit initialization of i2c_device_id::driver_data to 0 dropped
   from input drivers

 - other assorted fixes and cleanups.

dt-bindings: input: touchscreen: goodix: clarify irq-gpios misleading text

2024-01-21T05:04:23+00:00

The irq-gpios description misleading, apparently saying that driving the
IRQ GPIO resets the device, which is even more puzzling as there is a reset
GPIO as well.

In reality the IRQ pin can be driven during the reset sequence to configure
the client address, as it becomes clear after checking both the datasheet
and the driver code. Improve the text to clarify that.

Also rephrase to remove reference to the driver, which is not appropriate
in the bindings.
