This patch adds the DT bindings information for this hwspinlock
module.

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>;

		...

	};
