| Subject: FROMLIST: of: irq: document properties for wakeup interrupt parent |
| |
| Some interrupt controllers in a SoC, are always powered on and have a |
| select interrupts routed to them, so that they can wakeup the SoC from |
| suspend. Add wakeup-parent DT property to refer to these interrupt |
| controllers. |

| +-------------------------- |
| + |
| +Some interrupt controllers in a SoC, are always powered on and have a select |
| +interrupts routed to them, so that they can wakeup the SoC from suspend. These |
| +interrupt controllers do not fall into the category of a parent interrupt |
| +controller and can be specified by the "wakeup-parent" property and contain a |
| +single phandle referring to the wakeup capable interrupt controller. |
| + |
| + Example: |
| + wakeup-parent = <&pdc_intc>; |
