SIRF Hardware spinlock device Binding
|
|
-----------------------------------------------
|
|
|
|
Required properties :
|
|
- compatible : shall contain only one of the following:
|
|
"sirf,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.
|
|
|
|
Please look at the generic hwlock binding for usage information for consumers,
|
|
"Documentation/devicetree/bindings/hwlock/hwlock.txt"
|
|
|
|
Example of hwlock provider:
|
|
hwlock {
|
|
compatible = "sirf,hwspinlock";
|
|
reg = <0x13240000 0x00010000>;
|
|
#hwlock-cells = <1>;
|
|
};
|
|
|
|
Example of hwlock users:
|
|
node {
|
|
...
|
|
hwlocks = <&hwlock 2>;
|
|
...
|
|
};
