I remove the PMIC entry here because of the issues with this component i2c handling. More details at: http://www.active-semi.com/sheets/ACT8865_Datasheet.pdf The solution is to enable the desired regulators in the bootloader and then shut down the i2c interface completely. I'll do it while integrating the patch in my PR: no need to re-send.
