S5PV210's ADC variant is almost the same as v1 except that it has 10
channels and doesn't require the pmu register

This looks fine to me, but I'd like to let it sit on the lists
for a few days to let people more familiar with the platform have
time to review.

Give me a poke if I seem to have forgotten it in a week or so.

Thanks,

Jonathan

Long enough I thing ;)

Applied to the togreg branch of iio.git and pushed out as testing
for the autobuilders to play with it.
