1	* Renesas R-Car Gen2 Clock Pulse Generator (CPG)
2	
3	The CPG generates core clocks for the R-Car Gen2 SoCs. It includes three PLLs
4	and several fixed ratio dividers.
5	
6	Required Properties:
7	
8	  - compatible: Must be one of
9	    - "renesas,r8a7790-cpg-clocks" for the r8a7790 CPG
10	    - "renesas,r8a7791-cpg-clocks" for the r8a7791 CPG
11	    - "renesas,rcar-gen2-cpg-clocks" for the generic R-Car Gen2 CPG
12	
13	  - reg: Base address and length of the memory resource used by the CPG
14	
15	  - clocks: Reference to the parent clock
16	  - #clock-cells: Must be 1
17	  - clock-output-names: The names of the clocks. Supported clocks are "main",
18	    "pll0", "pll1", "pll3", "lb", "qspi", "sdh", "sd0", "sd1" and "z"
19
