+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>;
+};
