1 * Generic OPP Interface 2 3 SoCs have a standard set of tuples consisting of frequency and 4 voltage pairs that the device will support per voltage domain. These 5 are called Operating Performance Points or OPPs. 6 7 Properties: 8 - operating-points: An array of 2-tuples items, and each item consists 9 of frequency and voltage like <freq-kHz vol-uV>. 10 freq: clock frequency in kHz 11 vol: voltage in microvolt 12 13 Examples: 14 15 cpu@0 { 16 compatible = "arm,cortex-a9"; 17 reg = <0>; 18 next-level-cache = <&L2>; 19 operating-points = < 20 /* kHz uV */ 21 792000 1100000 22 396000 950000 23 198000 850000 24 >; 25 };
