| * 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 | |
