Merge tag 'input-for-v5.20-rc0' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input

Pull input updates from Dmitry Torokhov: - changes to input core to properly queue synthetic events (such as autorepeat) and to release multitouch contacts when an input device is inhibited or suspended - reworked quirk handling in i8042 driver that consolidates multiple DMI tables into one and adds several quirks for TUXEDO line of laptops - update to mt6779 keypad to better reflect organization of the hardware - changes to mtk-pmic-keys driver preparing it to handle more variants - facelift of adp5588-keys driver - improvements to iqs7222 driver - adjustments to various DT binding documents for input devices - other assorted driver fixes. * tag 'input-for-v5.20-rc0' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: (54 commits) Input: adc-joystick - fix ordering in adc_joystick_probe() dt-bindings: input: ariel-pwrbutton: use spi-peripheral-props.yaml Input: deactivate MT slots when inhibiting or suspending devices Input: properly queue synthetic events dt-bindings: input: iqs7222: Use central 'linux,code' definition Input: i8042 - add dritek quirk for Acer Aspire One AO532 dt-bindings: input: gpio-keys: accept also interrupt-extended dt-bindings: input: gpio-keys: reference input.yaml and document properties dt-bindings: input: gpio-keys: enforce node names to match all properties dt-bindings: input: Convert adc-keys to DT schema dt-bindings: input: Centralize 'linux,input-type' definition dt-bindings: input: Use common 'linux,keycodes' definition dt-bindings: input: Centralize 'linux,code' definition dt-bindings: input: Increase maximum keycode value to 0x2ff Input: mt6779-keypad - implement row/column selection Input: mt6779-keypad - match hardware matrix organization Input: i8042 - add additional TUXEDO devices to i8042 quirk tables Input: goodix - switch use of acpi_gpio_get_*_resource() APIs Input: i8042 - add TUXEDO devices to i8042 quirk tables Input: i8042 - add debug output for quirks ...

- - io-channels: Phandle to an ADC channel
- - io-channel-names = "buttons";
- - keyup-threshold-microvolt: Voltage above or equal to which all the keys are

-
-Optional properties:

-Each button (key) is represented as a sub-node of "adc-keys":

-No two values of press-threshold-microvolt may be the same.
-All values of press-threshold-microvolt must be less than
-keyup-threshold-microvolt.
