1 TI OMAP4 Wake-up Generator
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.
9 - compatible : should contain at least "ti,omap4-wugen-mpu" or
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 - interrupt-parent : a phandle to the GIC these interrupts are routed
20 - Because this HW ultimately routes interrupts to the GIC, the
21 interrupt specifier must be that of the GIC.
22 - Only SPIs can use the WUGEN as an interrupt parent. SGIs and PPIs
23 are explicitly forbidden.
