Wei Chen b97cadee80 DT: hwspinlock: add the CSR atlas7 hwspinlock bindings document
The Hardware Spinlock device on atlas7 provides hardware assistance
for synchronization between the multiple processors in the system
(dual Cortex-A7, CAN bus Cortex-M3 and audio DSP).
This patch adds the DT bindings information for this hwspinlock
module.

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>;
...
};
