Laurent Pinchart | 10cdfe9 | 2013-11-06 13:14:19 +0100 | [diff] [blame] | 1 | * Renesas R-Car Gen2 Clock Pulse Generator (CPG) |
| 2 | |
| 3 | The CPG generates core clocks for the R-Car Gen2 SoCs. It includes three PLLs |
| 4 | and several fixed ratio dividers. |
| 5 | |
| 6 | Required Properties: |
| 7 | |
| 8 | - compatible: Must be one of |
| 9 | - "renesas,r8a7790-cpg-clocks" for the r8a7790 CPG |
| 10 | - "renesas,r8a7791-cpg-clocks" for the r8a7791 CPG |

| 13 | |
| 14 | - reg: Base address and length of the memory resource used by the CPG |
| 15 | |
| 16 | - clocks: Reference to the parent clock |
| 17 | - #clock-cells: Must be 1 |
| 18 | - clock-output-names: The names of the clocks. Supported clocks are "main", |
| 19 | "pll0", "pll1", "pll3", "lb", "qspi", "sdh", "sd0", "sd1" and "z" |
| 20 | |
