[PATCH 09/47] gma500: initial medfield merge
Alan Cox
alan at lxorguk.ukuu.org.uk
Thu Mar 8 08:02:20 PST 2012
From: Kirill A. Shutemov <kirill.shutemov at linux.intel.com>
We need to merge this ahead of some of the cleanup because a lot of needed
cleanup spans both new and old chips. If we try and clean up and the merge
we end up fighting ourselves.
Signed-off-by: Kirill A. Shutemov <kirill.shutemov at linux.intel.com>
[With a load of the cleanup stuff folded in, register stuff reworked sanely]
