STM32 Hardware Spinlock Device Binding
-------------------------------------

Required properties :
- compatible : should be "st,stm32-hwspinlock".
- reg : the register address of hwspinlock.
- #hwlock-cells : should be <2> so the hwlock users use the hwlock id to
	represent a specific hwlock and define its shared / exclusive attribute.
- clock-names : Must contain "hsem".
- clocks : Must contain a phandle entry for the clock in clock-names, see the
	common clock bindings.

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

Example of hwlock provider:
	hwspinlock@4c000000 {
		compatible = "st,stm32-hwspinlock";
		#hwlock-cells = <2>;
		reg = <0x4c000000 0x400>;
		clocks = <&rcc HSEM>;
		clock-names = "hsem";
	};
