[PATCH 0/2] arm64: dts: allwinner: h6: Enable GPU and CPU DVFS on more boards

[Jernej Skrabec]

Most H6 boards don't use the GPU OPP table, and the Orange Pi One Plus
and Lite2 lack CPU DVFS as well, so their GPU and CPU run at a fixed
clock rate. This series enables both.

[PATCH 1/2] arm64: dts: allwinner: h6: Add GPU OPP table to all boards

[Jernej Skrabec]

Only the Beelink GS1 and TaiQiCat A01 include the H6 GPU OPP table, so
the GPU on all other H6 boards runs at a fixed clock rate. Include it on
the remaining boards, so devfreq can scale the GPU clock for either
better performance or lower power consumption.

The table also works with a fixed GPU supply, as on Tanix boards.

[PATCH 2/2] arm64: dts: allwinner: h6: orangepi: Enable CPU frequency scaling

[Jernej Skrabec]

The Orange Pi One Plus and Lite2 lack the CPU OPP table and CPU supply,
so the CPU never scales its frequency. Add both, like on Orange Pi 3.
OPPs above the regulator constraints stay unused.
