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.

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 };
