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).

Binding for the LTC2952 PowerPath controller
|
|
|
|
This chip is used to externally trigger a system shut down. Once the trigger has
|
|
been sent, the chip's watchdog has to be reset to gracefully shut down.
|
|
A full powerdown can be triggered via the kill signal.
|
|
|
|
Required properties:
|
|
|
|
- compatible: Must contain: "lltc,ltc2952"
|
|
- watchdog-gpios: phandle + gpio-specifier for the GPIO connected to the
|
|
chip's watchdog line
|
|
- kill-gpios: phandle + gpio-specifier for the GPIO connected to the
|
|
chip's kill line
|
|
|
|
Optional properties:
|
|
- trigger-gpios: phandle + gpio-specifier for the GPIO connected to the
|
|
chip's trigger line. If this property is not set, the
|
|
trigger function is ignored and the chip is kept alive
|
|
until an explicit kill signal is received
|
|
|
|
Example:
|
|
|
|
ltc2952 {
|
|
compatible = "lltc,ltc2952";
|
|
|
|
trigger-gpios = <&gpio0 1 GPIO_ACTIVE_LOW>;
|
|
watchdog-gpios = <&gpio1 2 GPIO_ACTIVE_HIGH>;
|
|
kill-gpios = <&gpio0 2 GPIO_ACTIVE_LOW>;
|
|
};
