* 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 */
