7 title: Rockchip Power Domains
10   - Elaine Zhang <zhangqing@rock-chips.com>

14   Rockchip processors include support for multiple power domains
16   application scenarios to save power.
18   Power domains contained within power-controller node are
19   generic power domain providers documented in
20   Documentation/devicetree/bindings/power/power-domain.yaml.
22   IP cores belonging to a power domain should contain a
23   "power-domains" property that is a phandle for the
24   power domain node representing the domain.
