| * Renesas RZ Clock Pulse Generator (CPG) |
| |
| The CPG generates core clocks for the RZ SoCs. It includes the PLL, variable |
| CPU and GPU clocks, and several fixed ratio dividers. |
| |
| Required Properties: |
| |
| - compatible: Must be one of |
| - "renesas,r7s72100-cpg-clocks" for the r7s72100 CPG |
| - "renesas,rz-cpg-clocks" for the generic RZ CPG |
| - reg: Base address and length of the memory resource used by the CPG |
| - clocks: References to possible parent clocks. Order must match clock modes |
| in the datasheet. For the r7s72100, this is extal, usb_x1. |
| - #clock-cells: Must be 1 |
| - clock-output-names: The names of the clocks. Supported clocks are "pll", |
| "i", and "g" |
| |
| |
| Example |
| ------- |
| |
| cpg_clocks: cpg_clocks@fcfe0000 { |
| #clock-cells = <1>; |
| compatible = "renesas,r7s72100-cpg-clocks", |
| "renesas,rz-cpg-clocks"; |
| reg = <0xfcfe0000 0x18>; |
| clocks = <&extal_clk>, <&usb_x1_clk>; |
| clock-output-names = "pll", "i", "g"; |
| }; |
