-* Renesas R-Car Gen2 Clock Pulse Generator (CPG)
-
-The CPG generates core clocks for the R-Car Gen2 SoCs. It includes three PLLs
-and several fixed ratio dividers.
-The CPG also provides a Clock Domain for SoC devices, in combination with the
-CPG Module Stop (MSTP) Clocks.
-
-Required Properties:
-
- - compatible: Must be one of
- - "renesas,r8a7790-cpg-clocks" for the r8a7790 CPG
- - "renesas,r8a7791-cpg-clocks" for the r8a7791 CPG
- - "renesas,r8a7792-cpg-clocks" for the r8a7792 CPG
- - "renesas,r8a7793-cpg-clocks" for the r8a7793 CPG
- - "renesas,r8a7794-cpg-clocks" for the r8a7794 CPG
- and "renesas,rcar-gen2-cpg-clocks" as a fallback.
-
- - reg: Base address and length of the memory resource used by the CPG
-
- - clocks: References to the parent clocks: first to the EXTAL clock, second
- to the USB_EXTAL clock
- - #clock-cells: Must be 1
- - clock-output-names: The names of the clocks. Supported clocks are "main",
- "pll0", "pll1", "pll3", "lb", "qspi", "sdh", "sd0", "sd1", "z", "rcan", and
- "adsp"
- - #power-domain-cells: Must be 0
-
-SoC devices that are part of the CPG/MSTP Clock Domain and can be power-managed
-through an MSTP clock should refer to the CPG device node in their
-"power-domains" property, as documented by the generic PM domain bindings in
-Documentation/devicetree/bindings/power/power_domain.txt.
