-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 "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>;
