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";
|
|
};
