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).

twl4030 GPIO controller bindings
|
|
|
|
Required properties:
|
|
- compatible:
|
|
- "ti,twl4030-gpio" for twl4030 GPIO controller
|
|
- #gpio-cells : Should be two.
|
|
- first cell is the pin number
|
|
- second cell is used to specify optional parameters (unused)
|
|
- gpio-controller : Marks the device node as a GPIO controller.
|
|
- #interrupt-cells : Should be 2.
|
|
- interrupt-controller: Mark the device node as an interrupt controller
|
|
The first cell is the GPIO number.
|
|
The second cell is not used.
|
|
- ti,use-leds : Enables LEDA and LEDB outputs if set
|
|
- ti,debounce : if n-th bit is set, debounces GPIO-n
|
|
- ti,mmc-cd : if n-th bit is set, GPIO-n controls VMMC(n+1)
|
|
- ti,pullups : if n-th bit is set, set a pullup on GPIO-n
|
|
- ti,pulldowns : if n-th bit is set, set a pulldown on GPIO-n
|
|
|
|
Example:
|
|
|
|
twl_gpio: gpio {
|
|
compatible = "ti,twl4030-gpio";
|
|
#gpio-cells = <2>;
|
|
gpio-controller;
|
|
#interrupt-cells = <2>;
|
|
interrupt-controller;
|
|
ti,use-leds;
|
|
};
