I no longer maintain an ep93xx tree because the architecture gets very
few patches now. Patches should go via the arm-soc tree, which is
maintained by (I believe) Arnd and Olaf.

Sure, the series looks fine to me. For the ep93xx specific bits:

The ep93xx architecture is old and obsolete. Because of this, and the
relatively few number of people developing for it and with hardware to
test, it hasn't gotten upgraded to some of the more modern kernel apis
like the common clock framework.

It probably isn't too difficult to move ep93xx to the common clock
framework, but it is a separate change and I don't think Alexander
should have to do it as a prerequisite to getting this adc support merged.
