The driver code (both mfd and regulator) have compile time dependencies
which need to go through the same tree Mark already reviewed the
regulator patches, so if you could take all the mfd and regulator
patches, that would be great.

Maxime already merged some of the dt patches. I still need to fix
up one comment, but he can merge them individually.

Thanks!
