From e2e022ec51a7e85ce4352a53fde1cd11d58e151a Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Tue, 20 Dec 2011 15:58:44 +0000 Subject: gma500/oaktrail: panel display quality fix The GCT setup was used on Moorestown. The Oaktrail version uses a normal PC interface. That means we must also honour the dither info from the BIOS data.
