Need to wait for the ARM, DT and I2C guys to review, at which point
I'll be happy to take in and supply a branch for them to pull from if
required. If there are no _true_ dependencies and the MFD changes can
be added independently without fear of build breakages, let me know
and I'll apply them separately.
