| 2 | |
| 3 | The PPL controller provides the 3 main clocks of the SoC: CPU, DDR and AHB. |
| 4 | |
| 5 | Required Properties: |
| 6 | - compatible: has to be "qca,<soctype>-pll" and one of the following |
| 7 | fallbacks: |
| 8 | - "qca,ar7100-pll" |
| 9 | - "qca,ar7240-pll" |
| 10 | - "qca,ar9130-pll" |
| 11 | - "qca,ar9330-pll" |
| 12 | - "qca,ar9340-pll" |
| 13 | - "qca,qca9550-pll" |
| 14 | - reg: Base address and size of the controllers memory area |
| 15 | - clock-names: Name of the input clock, has to be "ref" |
| 16 | - clocks: phandle of the external reference clock |
| 17 | - #clock-cells: has to be one |
| 18 | |
| 19 | Optional properties: |
| 20 | - clock-output-names: should be "cpu", "ddr", "ahb" |
| 21 | |
| 22 | Example: |
| 23 | |
| 24 | pll-controller@18050000 { |
| 25 | compatible = "qca,ar9132-pll", "qca,ar9130-pll"; |
| 26 | reg = <0x18050000 0x20>; |
| 27 | |
| 28 | clock-names = "ref"; |
| 29 | clocks = <&extosc>; |
| 30 | |
| 31 | #clock-cells = <1>; |
| 32 | clock-output-names = "cpu", "ddr", "ahb"; |
| 33 | }; |
