+TI OMAP4 Wake-up Generator
+
+All TI OMAP4/5 (and their derivatives) an interrupt controllerthat
+routes interrupts to the GIC, and also serves as a wakeup source. It
+is also refered to as "WUGEN-MPU", hence the name of the binding.
+
+Reguired properties:
+
+- compatible : should contain at least "ti,omap4-wugen-mpu"
+- reg : Specifies base physical address and size of the registers.
+- interrupt-controller : Identifies the node as an interrupt controller.
+- #interrupt-cells : Specifies the number of cells needed to encode an
+ interrupt source. The value must be 3.
+- interrupt-parent : a phandle to the GIC these interrupts are routed
+ to.
+
+Notes:
+
+- Because this HW ultimately routes interrupts to the GIC, the
+ interrupt specifier must be that of the GIC.
+- Only SPIs can use the ictlr as an interrupt parent. SGIs and PPIs
+ are explicitely forbiden.
+
+Example:
+
+ wakeupgen: interrupt-controller@48281000 {
+ compatible = "ti,omap5-wugen-mpu", "ti,omap4-wugen-mpu";
+ interrupt-controller;
+ #interrupt-cells = <3>;
+ reg = <0x48281000 0x1000>;
+ interrupt-parent = <&gic>;
+ };
