change in v2:
- use BSD-2-Clause license
- use const for #hwlock-cells
- add additionalProperties: false

-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>;
-		clocks = <&rcc HSEM>;
-		clock-names = "hsem";
-	};
