Hello,
I'm trying to upgrade my BananaPI to latest 5.x kernel. Unfortunately, it
doesn't support 3.5 LCD display as per it's DTS.
A found a patch from Paul Kocialkowski : https://lkml.org/lkml/2018/11/7/980
But despite responses saying patches have been committed, as said the DTS

Hi Sunxi maintainers and members,
Now that required drivers are merged we can contibute on DVFS

This serie is based on Yangtao Li serie[0] and Ondřej Jirman work[1].
Most of the OPP tables are taken from original vendor kernel[2].
Plus there is a new CPU frequencies at
Allwinner H6 needs this driver to be able to get
the correct speed_bin required for DVFS.
Enable this option in arm64 defconfig.

This needs to change the CPU regulator max voltage to fit

This enables passive cooling by down-regulating CPU voltage
and frequency.

This needs also to change the CPU regulator min/max voltage to fit
the OPP table.
