Alexander just pointed me to the series, I had missed it earlier.

The patches for arch/arm/mach-ep93xx look reasonable to me,
with one minor complaint: please use "ARM:" as the subject prefix.

Alexander, can you send a pull request for the first four patches
to arm at kernel.org, or a set of patches if that is easier for you?

I think the adc driver can just get merged through the iio tree,
as there is no strict build-time dependency. I realize the driver
will fail to link when built on ep93xx or another platform that lacks
the clk_get_parent() implementation, but I think that's ok since
we have an old bug in several platforms concerning this, and
I have proposed a fix for it already.
