    1 TI OMAP4 Wake-up Generator
    2 
    3 All TI OMAP4/5 (and their derivatives) an interrupt controller that
    4 routes interrupts to the GIC, and also serves as a wakeup source. It
    5 is also referred to as "WUGEN-MPU", hence the name of the binding.
    6 
    7 Required properties:
    8 
    9 - compatible : should contain at least "ti,omap4-wugen-mpu" or
   10   "ti,omap5-wugen-mpu"
   11 - reg : Specifies base physical address and size of the registers.
   12 - interrupt-controller : Identifies the node as an interrupt controller.
   13 - #interrupt-cells : Specifies the number of cells needed to encode an
   14   interrupt source. The value must be 3.
   15 
   16 Notes:
   17 
   18 - Because this HW ultimately routes interrupts to the GIC, the
   19   interrupt specifier must be that of the GIC.
   20 - Only SPIs can use the WUGEN as an interrupt parent. SGIs and PPIs
   21   are explicitly forbidden.
   22 
   23 Example:
   24 
   25        wakeupgen: interrupt-controller@48281000 {
   26                compatible = "ti,omap5-wugen-mpu", "ti,omap4-wugen-mpu";
   27                interrupt-controller;
   28                #interrupt-cells = <3>;
   29                reg = <0x48281000 0x1000>;
   30                interrupt-parent = <&gic>;
   31        };
