1* Renesas R8A73A4 Clock Pulse Generator (CPG)
2
3The CPG generates core clocks for the R8A73A4 SoC. It includes five PLLs
4and several fixed ratio dividers.
5
6Required Properties:
7
8  - compatible: Must be "renesas,r8a73a4-cpg-clocks"
9
10  - reg: Base address and length of the memory resource used by the CPG
11
12  - clocks: Reference to the parent clocks ("extal1" and "extal2")
13
14  - #clock-cells: Must be 1
15
16  - clock-output-names: The names of the clocks. Supported clocks are "main",
17    "pll0", "pll1", "pll2", "pll2s", "pll2h", "z", "z2", "i", "m3", "b",
18    "m1", "m2", "zx", "zs", and "hp".
