* Renesas R8A73A4 Clock Pulse Generator (CPG)

The CPG generates core clocks for the R8A73A4 SoC. It includes five PLLs
and several fixed ratio dividers.

Required Properties:

  - compatible: Must be "renesas,r8a73a4-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", "pll2s", "pll2h", "z", "z2", "i", "m3", "b",
    "m1", "m2", "zx", "zs", and "hp".


Example
-------

        cpg_clocks: cpg_clocks@e6150000 {
                compatible = "renesas,r8a73a4-cpg-clocks";
                reg = <0 0xe6150000 0 0x10000>;
                clocks = <&extal1_clk>, <&extal2_clk>;
                #clock-cells = <1>;
                clock-output-names = "main", "pll0", "pll1", "pll2",
                                     "pll2s", "pll2h", "z", "z2",
                                     "i", "m3", "b", "m1", "m2",
                                     "zx", "zs", "hp";
        };
