| description: > |
| 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. |
