The R8A7779 SoC has several clocks that are too custom to be supported in a generic driver. Those clocks are all fixed rate clocks with multiplier and divisor set according to boot mode configuration. Based on work for R-Car Gen2 SoCs by Laurent Pinchart.

* Renesas R8A7779 Clock Pulse Generator (CPG)
|
|
|
|
The CPG generates core clocks for the R8A7779. It includes one PLL and
|
|
several fixed ratio dividers
|
|
|
|
Required Properties:
|
|
|
|
- compatible: Must be "renesas,r8a7779-cpg-clocks"
|
|
- reg: Base address and length of the memory resource used by the CPG
|
|
|
|
- clocks: Reference to the parent clock
|
|
- #clock-cells: Must be 1
|
|
- clock-output-names: The names of the clocks. Supported clocks are "plla",
|
|
"z", "zs", "s", "s1", "p", "b", "out".
|
|
|
|
|
|
Example
|
|
-------
|
|
|
|
cpg_clocks: cpg_clocks@ffc80000 {
|
|
compatible = "renesas,r8a7779-cpg-clocks";
|
|
reg = <0 0xffc80000 0 0x30>;
|
|
clocks = <&extal_clk>;
|
|
#clock-cells = <1>;
|
|
clock-output-names = "plla", "z", "zs", "s", "s1", "p",
|
|
"b", "out";
|
|
};
