This patchset imports simple DVFS support for Allwinner A64 SoC.

As the thermal sensor driver is not yet implemented and some boards
have still no AXP PMIC support, now only two OPPs are present --
648MHz@1.04V and 816MHz@1.1V to prevent overheat or undervoltage.

PATCH 1 is a fix to the CCU driver of A64, and the remaining patches
set up the device tree bits of the DVFS on Pine64.

How has this been tested?

What tasks did you run, with what governor, etc...

I only tested manual frequency switching between 648MHz and
816MHz, and tested the PLL stuck issue by change the OPPs to
some random value.

Thanks!
Maxime
