		SIRF Hardware spinlock device Binding
		-----------------------------------------------

		Required properties :
		- compatible : shall contain only one of the following:
		"sirf,hwspinlock"

		- reg : the register address of hwspinlock

		- #hwlock-cells : hwlock users only use the hwlock id to represent a specific
		hwlock, so the number of cells should be <1> here.

		Please look at the generic hwlock binding for usage information for consumers,
		"Documentation/devicetree/bindings/hwlock/hwlock.txt"

		Example of hwlock provider:
		hwlock {
		compatible = "sirf,hwspinlock";
		reg = <0x13240000 0x00010000>;
		#hwlock-cells = <1>;
		};

		Example of hwlock users:
		node {
		...
		hwlocks = <&hwlock 2>;
		...
		};
