From: "Dr. David Alan Gilbert" <linux@treblig.org>

The pcf50633 was used as part of the OpenMoko devices but
the support for its main chip was recently removed in:
commit 61b7f8920b17 ("ARM: s3c: remove all s3c24xx support")

See https://lore.kernel.org/all/Z8z236h4B5A6Ki3D@gallifrey/

Remove it.

I've split this up based on the subcomponents to make the size
of each patch sensible.

Dave

If you would separate by subsystem, this would be easier to apply. I
don't think the mfd changes are necessary from a bisection point of
view.
