* Renesas R-Car Gen2 Clock Pulse Generator (CPG)
The CPG generates core clocks for the R-Car Gen2 SoCs. It includes three PLLs
and several fixed ratio dividers.
Required Properties:
- compatible: Must be one of
- "renesas,r8a7790-cpg-clocks" for the r8a7790 CPG
- "renesas,r8a7791-cpg-clocks" for the r8a7791 CPG
- "renesas,r8a7793-cpg-clocks" for the r8a7793 CPG
- "renesas,r8a7794-cpg-clocks" for the r8a7794 CPG
and "renesas,rcar-gen2-cpg-clocks" as a fallback.
- reg: Base address and length of the memory resource used by the CPG
- clocks: References to the parent clocks: first to the EXTAL clock, second
to the USB_EXTAL clock
- #clock-cells: Must be 1
- clock-output-names: The names of the clocks. Supported clocks are "main",
"pll0", "pll1", "pll3", "lb", "qspi", "sdh", "sd0", "sd1", "z", "rcan", and
"adsp"
Example
-------
cpg_clocks: cpg_clocks@e6150000 {
compatible = "renesas,r8a7790-cpg-clocks",
"renesas,rcar-gen2-cpg-clocks";
reg = <0 0xe6150000 0 0x1000>;
clocks = <&extal_clk &usb_extal_clk>;
#clock-cells = <1>;
clock-output-names = "main", "pll0, "pll1", "pll3",
"lb", "qspi", "sdh", "sd0", "sd1", "z",
"rcan", "adsp";
};
