> +TI OMAP4 Wake-up Generator
> +
> +All TI OMAP4/5 (and their derivatives) an interrupt controller that
> +routes interrupts to the GIC, and also serves as a wakeup source. It
> +is also referred to as "WUGEN-MPU", hence the name of the binding.
> +
> +Reguired properties:
> +
> +- compatible : should contain at least "ti,omap4-wugen-mpu" or
> + "ti,omap5-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 WUGEN as an interrupt parent. SGIs and PPIs
> + are explicitly 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>;
