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.
|
|
|
|
Required 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.
|
|
|
|
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 forbidden.
|
|
|
|
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>;
|
|
};
