12description: >
13  All TI OMAP4/5 (and their derivatives) are interrupt controllers that route
14  interrupts to the GIC, and also serve as wakeup sources. They are also
15  referred to as "WUGEN-MPU", hence the name of the binding.
16
17  Notes:
18
19    - Because this HW ultimately routes interrupts to the GIC, the interrupt
20      specifier must be that of the GIC.
21    - Only SPIs can use the WUGEN as an interrupt parent. SGIs and PPIs are
22      explicitly forbidden.
