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:

15	cpu@0 {
16		compatible = "arm,cortex-a9";
17		reg = <0>;
18		next-level-cache = <&L2>;
19		operating-points = <
