* Renesas SH73A0 Clock Pulse Generator (CPG)

The CPG generates core clocks for the SH73A0 SoC. It includes four PLLs
and several fixed ratio dividers.

Required Properties:

  - compatible: Must be "renesas,sh73a0-cpg-clocks"

  - reg: Base address and length of the memory resource used by the CPG

  - clocks: Reference to the parent clocks ("extal1" and "extal2")

  - #clock-cells: Must be 1

  - clock-output-names: The names of the clocks. Supported clocks are "main",
    "pll0", "pll1", "pll2", "pll3", "dsi0phy", "dsi1phy", "zg", "m3", "b",
    "m1", "m2", "z", "zx", and "hp".


Example
-------

        cpg_clocks: cpg_clocks@e6150000 {
                compatible = "renesas,sh73a0-cpg-clocks";
                reg = <0 0xe6150000 0 0x10000>;
                clocks = <&extal1_clk>, <&extal2_clk>;
                #clock-cells = <1>;
                clock-output-names = "main", "pll0", "pll1", "pll2",
                                     "pll3", "dsi0phy", "dsi1phy",
                                     "zg", "m3", "b", "m1", "m2",
                                     "z", "zx", "hp";
        };
