1Binding for the LTC2952 PowerPath controller2 3This chip is used to externally trigger a system shut down. Once the trigger has4been sent, the chip's watchdog has to be reset to gracefully shut down.5A full powerdown can be triggered via the kill signal.6 7Required properties:8 9- compatible: Must contain: "lltc,ltc2952"10- watchdog-gpios: phandle + gpio-specifier for the GPIO connected to the11 chip's watchdog line12- kill-gpios: phandle + gpio-specifier for the GPIO connected to the13 chip's kill line14 15Optional properties:16- trigger-gpios: phandle + gpio-specifier for the GPIO connected to the17 chip's trigger line. If this property is not set, the18 trigger function is ignored and the chip is kept alive19 until an explicit kill signal is received20- trigger-delay-ms The number of milliseconds to wait after trigger line21 assertion before executing shut down procedure.22 The default is 2500ms.23 24Example:25 26ltc2952 {27 compatible = "lltc,ltc2952";28 29 trigger-gpios = <&gpio0 1 GPIO_ACTIVE_LOW>;30 trigger-delay-ms = <2000>;31 watchdog-gpios = <&gpio1 2 GPIO_ACTIVE_HIGH>;32 kill-gpios = <&gpio0 2 GPIO_ACTIVE_LOW>;33};34
