| * 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"; |
| }; |
