1STM32 Hardware Spinlock Device Binding
2-------------------------------------
3
4Required properties :
5- compatible : should be "st,stm32-hwspinlock".
6- reg : the register address of hwspinlock.
7- #hwlock-cells : hwlock users only use the hwlock id to represent a specific
8 hwlock, so the number of cells should be <1> here.
9- clock-names : Must contain "hsem".
10- clocks : Must contain a phandle entry for the clock in clock-names, see the
11 common clock bindings.

13Please look at the generic hwlock binding for usage information for consumers,
14"Documentation/devicetree/bindings/hwlock/hwlock.txt"

16Example of hwlock provider:
17 hwspinlock@4c000000 {
18 compatible = "st,stm32-hwspinlock";
19 #hwlock-cells = <1>;
20 reg = <0x4c000000 0x400>;
21 clocks = <&rcc HSEM>;
22 clock-names = "hsem";
23 };
