From: Wei Chen <wei.c...@csr.com>
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
+
+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>;
+ ...
