Binding for the LTC2952 PowerPath controller
|
|
|
|
This chip is used to externally trigger a system shut down. Once the trigger has
|
|
been sent, the chips' watchdog has to be reset to gracefully shut down.
|
|
If the Linux systems decides to shut down it powers off the platform via the
|
|
kill signal.
|
|
|
|
Required properties:
|
|
|
|
- compatible: Must contain: "lltc,ltc2952"
|
|
- trigger-gpios: phandle + gpio-specifier for the GPIO connected to the
|
|
chip's trigger line
|
|
- 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
|
|
|
|
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>;
|
|
};
