* 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
