The series adding MFD driver for these PMICs is available here [1]. Please note that this series depends on that one. The motivation and testing platform for this is the samsung,coreprimevelte smartphone for which the initial support efforts are ongoing here [2]. This PMIC is also found in at least two other devices with the PXA1908 SoC, such as samsung,xcover3lte and samsung,grandprimevelte. As the only reference for this driver served the smartphone's downstream kernel tree which is available here [3]. Please note that the first patch of this series is just a joining step with respect to series [1] and will be amalgated with future versions of it and dropped here. Also please note that that this series has the same defects as the MFD one and thus please only review the new parts. Lastly, as I would like to get some feedback on whether the approach I have taken here is OK, I have only defined descriptions for three regulators so far, the remaining eighteen will be defined in the same style and will of course be added when this series leaves the RFC state at the latest.
