I have no problem with this (and the current "dts" file I see don't go
this low anyway), but it doesn't match the datasheet I have right now
which says "0.700 V" is the min.
Then it would be problem.
The original statement above says, that a register value of "0" equals 700mV,
so changing this in this way would mean everything runs 12.5mV above the
target voltage.
And I can confirm, that the current datasheet lists 700mV as equallying
register value 0.
Has anyone got a voltmeter?
The latest datasheet has fixed this error.
The register value of "0" equals 712.5mV, so the max value can reach
1.5v but not 1.4875v.
