All TI OMAP4/5 (and their derivatives) are interrupt controllers that route
|
|
interrupts to the GIC, and also serve as wakeup sources. They are also
|
|
referred to as "WUGEN-MPU", hence the name of the binding.
|
|
|
|
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.
