I just used the limits from the pmic datasheet at the time as there were no other boards with axp209 regulator defined, no fex file for the lime2 etc. I likely would have sent a full respin based on your patches, but as only bits have been applied it seemed better to do this minimal one and fix the rest properly later. I can do a couple of the other Olimex boards that I have available to test while I'm doing it. Iain
