-* Renesas R8A7779 Clock Pulse Generator (CPG)
-
-The CPG generates core clocks for the R8A7779. It includes one PLL 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 "renesas,r8a7779-cpg-clocks"
- - reg: Base address and length of the memory resource used by the CPG
-
- - clocks: Reference to the parent clock
- - #clock-cells: Must be 1
- - clock-output-names: The names of the clocks. Supported clocks are "plla",
- "z", "zs", "s", "s1", "p", "b", "out".
- - #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.

-Examples
---------
-
- - CPG device node:
-
- cpg_clocks: cpg_clocks@ffc80000 {
- compatible = "renesas,r8a7779-cpg-clocks";
- reg = <0xffc80000 0x30>;
- clocks = <&extal_clk>;
- #clock-cells = <1>;
- clock-output-names = "plla", "z", "zs", "s", "s1", "p",
- "b", "out";
- #power-domain-cells = <0>;
- };
-
-
- - CPG/MSTP Clock Domain member device node:
-
- sata: sata@fc600000 {
- compatible = "renesas,sata-r8a7779", "renesas,rcar-sata";
- reg = <0xfc600000 0x2000>;
- interrupts = <0 100 IRQ_TYPE_LEVEL_HIGH>;
- clocks = <&mstp1_clks R8A7779_CLK_SATA>;
- power-domains = <&cpg_clocks>;
- };
