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";
};
