@Maxime: How should we handle this? In its current form, the patch applies
only to the BananaPi dts by overriding the inherited opp from the SoC dtsi.
In an earlier discussion, it was said that this can be done, even though it
might not be the most elegant approach. But then again, I think it
shouldn't be necessary to change the opp in the sun7i-a20.dtsi for all A20
boards since this is - to my knowledge - the first and only report that an
A20 board has stability issues at the lower voltages (although not too many
boards use voltage scaling yet).
IIUC this setting doesn't affect signals external to the A20, so it
seems like it should be board-agnostic.
This setting configures the voltage at the pmic output pin, not at the SoC
power-input pins. And how much of the voltage actually makes it from the pmic
to the SoC definitely is board-specific. So we are going to need board-specific
opp-s in some cases (like this one for example).

Hans
