+OMAP4+ HwSpinlock Driver
+========================
+
+Required properties:
+- compatible: Should be "ti,omap4-hwspinlock" for
+ OMAP44xx, OMAP54xx, AM33xx, AM43xx, DRA7xx SoCs
+- reg: Contains the hwspinlock module register address space
+ (base address and length)
+- ti,hwmods: Name of the hwmod associated with the hwspinlock device
+- #hwlock-cells: Should be 1. The OMAP hwspinlock users will use a
+ 0-indexed relative hwlock number as the argument
+ specifier value for requesting a specific hwspinlock
+ within a hwspinlock bank.
+
+Please look at the generic hwlock binding for usage information for consumers,
+"Documentation/devicetree/bindings/hwlock/hwlock.txt"
+
+Example:
+
+/* OMAP4 */
+hwspinlock: spinlock@4a0f6000 {
+ compatible = "ti,omap4-hwspinlock";
+ reg = <0x4a0f6000 0x1000>;
+ ti,hwmods = "spinlock";
+ #hwlock-cells = <1>;
+};
