DT bindings for the Renesas R-Car (RZ/G) System Controller
|
|
|
|
== System Controller Node ==
|
|
|
|
The R-Car (RZ/G) System Controller provides power management for the CPU cores
|
|
and various coprocessors.
|
|
|
|
Required properties:
|
|
- compatible: Must contain exactly one of the following:
|
|
- "renesas,r8a7743-sysc" (RZ/G1M)
|
|
- "renesas,r8a7745-sysc" (RZ/G1E)
|
|
- "renesas,r8a77470-sysc" (RZ/G1C)
|
|
- "renesas,r8a7779-sysc" (R-Car H1)
|
|
- "renesas,r8a7790-sysc" (R-Car H2)
|
|
- "renesas,r8a7791-sysc" (R-Car M2-W)
|
|
- "renesas,r8a7792-sysc" (R-Car V2H)
|
|
- "renesas,r8a7793-sysc" (R-Car M2-N)
|
|
- "renesas,r8a7794-sysc" (R-Car E2)
|
|
- "renesas,r8a7795-sysc" (R-Car H3)
|
|
- "renesas,r8a7796-sysc" (R-Car M3-W)
|
|
- "renesas,r8a77965-sysc" (R-Car M3-N)
|
|
- "renesas,r8a77970-sysc" (R-Car V3M)
|
|
- "renesas,r8a77980-sysc" (R-Car V3H)
|
|
- "renesas,r8a77990-sysc" (R-Car E3)
|
|
- "renesas,r8a77995-sysc" (R-Car D3)
|
|
- reg: Address start and address range for the device.
|
|
- #power-domain-cells: Must be 1.
|
|
|
|
|
|
Example:
|
|
|
|
sysc: system-controller@e6180000 {
|
|
compatible = "renesas,r8a7791-sysc";
|
|
reg = <0 0xe6180000 0 0x0200>;
|
|
#power-domain-cells = <1>;
|
|
};
|
|
|
|
|
|
== PM Domain Consumers ==
|
|
|
|
Devices residing in a power area must refer to that power area, as documented
|
|
by the generic PM domain bindings in
|
|
Documentation/devicetree/bindings/power/power_domain.txt.
|
|
|
|
Required properties:
|
|
- power-domains: A phandle and symbolic PM domain specifier, as defined in
|
|
<dt-bindings/power/r8a77*-sysc.h>.
|
|
|
|
|
|
Example:
|
|
|
|
L2_CA15: cache-controller@0 {
|
|
compatible = "cache";
|
|
power-domains = <&sysc R8A7791_PD_CA15_SCU>;
|
|
cache-unified;
|
|
cache-level = <2>;
|
|
};
