From: Måns Andersson <mans.andersson@nibe.se>

The data sheet statement that DCDC1 and DCDC3 only can be set in the range
0.9V - 1.5V refers to storage on its internal EEPROM and therefore cold boot
configuration. After power-on the device can be reconfigured over i2c and
DCDC1/3 set up to 3.3V.

Your git configuration is broken, you don't provide an e-mail address in
the From.  Please check this and fix for future submissions, it's
confusing and a bit of a red flag.
