1DT bindings for the Renesas R-Car (RZ/G) System Controller
2
3== System Controller Node ==
4
5The R-Car (RZ/G) System Controller provides power management for the CPU cores
6and various coprocessors.
7
8Required properties:
9 - compatible: Must contain exactly one of the following:
10 - "renesas,r8a7743-sysc" (RZ/G1M)
11 - "renesas,r8a7745-sysc" (RZ/G1E)
12 - "renesas,r8a7779-sysc" (R-Car H1)
13 - "renesas,r8a7790-sysc" (R-Car H2)
14 - "renesas,r8a7791-sysc" (R-Car M2-W)
15 - "renesas,r8a7792-sysc" (R-Car V2H)
16 - "renesas,r8a7793-sysc" (R-Car M2-N)
17 - "renesas,r8a7794-sysc" (R-Car E2)
18 - "renesas,r8a7795-sysc" (R-Car H3)
19 - "renesas,r8a7796-sysc" (R-Car M3-W)
20 - reg: Address start and address range for the device.
21 - #power-domain-cells: Must be 1.
22
23
24Example:
25
26 sysc: system-controller@e6180000 {
27 compatible = "renesas,r8a7791-sysc";
28 reg = <0 0xe6180000 0 0x0200>;
29 #power-domain-cells = <1>;
30 };

33== PM Domain Consumers ==
34
35Devices residing in a power area must refer to that power area, as documented
36by the generic PM domain bindings in
37Documentation/devicetree/bindings/power/power_domain.txt.
38
39Required properties:
40 - power-domains: A phandle and symbolic PM domain specifier, as defined in
41 <dt-bindings/power/r8a77*-sysc.h>.
42
43
44Example:
45
46 L2_CA15: cache-controller@0 {
47 compatible = "cache";
48 power-domains = <&sysc R8A7791_PD_CA15_SCU>;
49 cache-unified;
50 cache-level = <2>;
51 };
