+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".

"hwspinlock" --> "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 = <1>;
+               reg = <0x4c000000 0x400>;
+               clocks = <&rcc HSEM>;
+               clock-names = "hsem";
+       };
