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
