[PATCH v1 1/4] arm64: defconfig: Enable devfreq cooling device

[Konstantin Ryabitsev]

From: Clément Péron <peron.clem@gmail.com>

Devfreq cooling device framework is used in Panfrost
to throttle GPU in order to regulate its temperature.

Enable this driver for ARM64 SoC.

[PATCH v1 3/4] arm64: dts: allwinner: h6: Add GPU OPP table

[Konstantin Ryabitsev]

From: Clément Péron <peron.clem@gmail.com>

Add an Operating Performance Points table for the GPU to
enable Dynamic Voltage & Frequency Scaling on the H6.

The voltage range is set with minival voltage set to the target
and the maximal voltage set to 1.2V. This allow DVFS framework to
work properly on board with fixed regulator.
