Add devicetree binding document for rockchip reboot nofifier driver
Just reading the subject this is way too specific to the Linux driver needs rather than a h/w description. Please don't create fake DT nodes just to bind to drivers. Whatever &pmu is is probably what should have the DT node. Let the driver for it create child devices if you need that. Rob
