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>; + }; |
