5 - clocks: Must contain an entry for the CPU clock.
6   See ../clocks/clock-bindings.txt for details.
7 - operating-points-v2: See ../bindings/opp/opp-v2.yaml for details.
8 - #cooling-cells: Should be 2. See ../thermal/thermal-cooling-devices.yaml for details.
10 For each opp entry in 'operating-points-v2' table:
11 - opp-supported-hw: Two bitfields indicating:
21 	matches, the OPP gets enabled.
23 - opp-microvolt: CPU voltage triplet.
26 - cpu-supply: Phandle to the CPU power supply.
