Hi again,

one more thing...

If we stick to the standard operating points, shouldn't we honor their voltages
as well? If we set the minimum voltage for dcdc2 to 1.0V (as you did) or 1.05V
(as I did), this means that the lowest operating point of 144MHz at 0.9V defined
in sun7i-a20.dtsi (and with my definition the 312MHz opp as well) will not be
available because cpufreq-dt simply ignores operating points that aren't within
the set voltage range for that regulator.


Regards,

Timo
