+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>;
+};

+Generic SYSCON mapped register reset driver
+
+This is a generic reset driver using syscon to map the reset register.
+The reset is generally performed with a write to the reset register
+defined by the register map pointed by syscon reference plus the offset
+with the mask defined in the reboot node.
+
+Required properties:
+- compatible: should contain "syscon-reboot"
+- regmap: this is phandle to the register map node
+- offset: offset in the register map for the reboot register (in bytes)
+- mask: the reset value written to the reboot register (32 bit access)
+
+Default will be little endian mode, 32 bit access only.
+
+Examples:
+
+	reboot {
+	   compatible = "syscon-reboot";
+	   regmap = <&regmapnode>;
+	   offset = <0x0>;
+	   mask = <0x1>;
+	};
