| * Generic OPP Interface |
| |
| SoCs have a standard set of tuples consisting of frequency and |
| voltage pairs that the device will support per voltage domain. These |
| are called Operating Performance Points or OPPs. |
| |
| Properties: |
| - operating-points: An array of 2-tuples items, and each item consists |
| of frequency and voltage like <freq-kHz vol-uV>. |
| freq: clock frequency in kHz |
| vol: voltage in microvolt |
| |
| Examples: |
| |
| cpu@0 { |
| compatible = "arm,cortex-a9"; |
| reg = <0>; |
| next-level-cache = <&L2>; |
| operating-points = < |
| /* kHz uV */ |
| 792000 1100000 |
| 396000 950000 |
| 198000 850000 |
