Convert the TI Wakeup Generator interrupt controller binding to schema format. It's a straight-forward conversion of the typical interrupt controller. Link: https://lore.kernel.org/r/20250505144913.1293967-1-robh@kernel.org Signed-off-by: Rob Herring (Arm) <robh@kernel.org>

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.
