+STM32 Hardware Spinlock Device Binding
+-------------------------------------
+
+Required properties :
+- compatible : should be "st,stm32-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.
+- clock-names : Must contain "hwspinlock".
+- 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:

+ #hwlock-cells = <1>;
+ reg = <0x4c000000 0x400>;
