- * 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
