SPRD Hardware Spinlock Device Binding
-------------------------------------
Required properties :
- compatible : should be "sprd,hwspinlock-r3p0".
- 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 "enable".
- 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@40500000 {
compatible = "sprd,hwspinlock-r3p0";
reg = <0 0x40500000 0 0x1000>;
#hwlock-cells = <1>;
clock-names = "enable";
clocks = <&clk_aon_apb_gates0 22>;
};
