Just curious, the base arm voltage is (reported as) 0.80125 without special over_voltage set.
Is this the nominal (or close) volts specified for the Pi4 SoC ?
Is this base voltage also a hard minimum, or else will the Arm tolerate some amount of
under_voltage (aka "negative" over_voltage), and if it will : then how do you specify it ? Might be usefull when also under-clocking.
