Squashed backup commit (no shallow-clone history issues) of xiaomi-mt6833-dev/kernel_xiaomi_mt6833 (lineage-23.2 branch, upstream commit 9eece662e) plus all fixes applied to get everpal_defconfig building clean against a modern (GCC 15.2.0) toolchain -- see the previous commit message on the lineage-23.2 branch (also in this repo history is not available here since this is a squashed snapshot; full incremental history lives in the local DL380 checkout and the upstream GitHub remote).

Cypress I2C Touchpad
|
|
|
|
Required properties:
|
|
- compatible: must be "cypress,cyapa".
|
|
- reg: I2C address of the chip.
|
|
- interrupt-parent: a phandle for the interrupt controller (see interrupt
|
|
binding[0]).
|
|
- interrupts: interrupt to which the chip is connected (see interrupt
|
|
binding[0]).
|
|
|
|
Optional properties:
|
|
- wakeup-source: touchpad can be used as a wakeup source.
|
|
- pinctrl-names: should be "default" (see pinctrl binding [1]).
|
|
- pinctrl-0: a phandle pointing to the pin settings for the device (see
|
|
pinctrl binding [1]).
|
|
- vcc-supply: a phandle for the regulator supplying 3.3V power.
