2022-10-09Input: i8042 - rename i8042-x86ia64io.h to i8042-acpipnpio.hHuacai Chen
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.

2022-10-09Input: pinephone-keyboard - support the proxied I2C busSamuel Holland
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.

2022-09-30dt-bindings: input: Convert hid-over-i2c to DT schemaRob Herring
Convert the hid-over-i2c binding to DT schema format. The supplies should probably be specific to a specific device, but it seems they are already in use otherwise. 'wakeup-source' is added as it was not explicitly documented. There's a few warnings for undocumented properties 'vcc-supply' and 'reset-gpios'. Those remain as they probably should have a specific compatible as well.

2022-09-14Input: iqs7222 - set all ULP entry masks by defaultJeff LaBundy
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.
