* Renesas R8A7740 Clock Pulse Generator (CPG)
The CPG generates core clocks for the R8A7740 SoC. It includes three PLLs
and several fixed ratio and variable ratio dividers.
Required Properties:
- compatible: Must be "renesas,r8a7740-cpg-clocks"
- reg: Base address and length of the memory resource used by the CPG
- clocks: Reference to the three parent clocks
- #clock-cells: Must be 1
- clock-output-names: The names of the clocks. Supported clocks are
"system", "pllc0", "pllc1", "pllc2", "r", "usb24s", "i", "zg", "b",
"m1", "hp", "hpp", "usbp", "s", "zb", "m3", and "cp".
- renesas,mode: board-specific settings of the MD_CK* bits
Example
-------
cpg_clocks: cpg_clocks@e6150000 {
compatible = "renesas,r8a7740-cpg-clocks";
reg = <0xe6150000 0x10000>;
clocks = <&extal1_clk>, <&extal2_clk>, <&extalr_clk>;
#clock-cells = <1>;
clock-output-names = "system", "pllc0", "pllc1",
"pllc2", "r",
"usb24s",
"i", "zg", "b", "m1", "hp",
"hpp", "usbp", "s", "zb", "m3",
"cp";
};
&cpg_clocks {
renesas,mode = <0x05>;
};
