Rockchip HW Spinlock Device Binding
===================================
Required properties :
- compatible : shall contain only one of the following:
"rockchip,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.
- rockchip,hwlock-num-locks number of hwlocks provided by this device.
Optional properties :
- rockchip,hwlock-user-id : Set hwlock user id (4 bit, default is 0x01).
Please look at the generic hwlock binding for usage information for consumers,
"Documentation/devicetree/bindings/hwlock/hwlock.txt"
Example of hwlock provider:
hwlock: hwspinlock@ff040000 {
compatible = "rockchip,hwspinlock";
reg = <0 0xff040000 0 0x10000>;
#hwlock-cells = <1>;
rockchip,hwlock-num-locks = <64>;
};
Example of hwlock users:
node {
...
hwlocks = <&hwlock 0>;
...
};
