30Example:
31
32	sysc: system-controller@e6180000 {
33		compatible = "renesas,r8a7791-sysc";
34		reg = <0 0xe6180000 0 0x0200>;
35		#power-domain-cells = <1>;

41Devices residing in a power area must refer to that power area, as documented
42by the generic PM domain bindings in
43Documentation/devicetree/bindings/power/power_domain.txt.
44
45Required properties:
46  - power-domains: A phandle and symbolic PM domain specifier, as defined in
47		   <dt-bindings/power/r8a77*-sysc.h>.

50Example:
51
52	L2_CA15: cache-controller@0 {
53		compatible = "cache";
54		power-domains = <&sysc R8A7791_PD_CA15_SCU>;
55		cache-unified;
56		cache-level = <2>;
