+* 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";
+ };
