1These bindings should be considered EXPERIMENTAL for now.

3* Renesas SH73A0 Clock Pulse Generator (CPG)
4
5The CPG generates core clocks for the SH73A0 SoC. It includes four PLLs
6and several fixed ratio dividers.
7
8Required Properties:
9
10  - compatible: Must be "renesas,sh73a0-cpg-clocks"
11
12  - reg: Base address and length of the memory resource used by the CPG
13
14  - clocks: Reference to the parent clocks ("extal1" and "extal2")
15
16  - #clock-cells: Must be 1
17
18  - clock-output-names: The names of the clocks. Supported clocks are "main",
19    "pll0", "pll1", "pll2", "pll3", "dsi0phy", "dsi1phy", "zg", "m3", "b",
20    "m1", "m2", "z", "zx", and "hp".
