From dc8498c00f6a41a28f01111a3d2ed9f179356a71 Mon Sep 17 00:00:00 2001 From: InKi Dae Date: Tue, 10 Aug 2010 18:02:32 -0700 Subject: [PATCH] s3c-fb: fix distortedness situation for the mode more then 24bpp It has been working fine at 16bpp but in case of pixel format more then 24bpp it would occur distortedness situation on that mode. so this patch set the word swap control bit of WINCONx to 1 as default value. but it should be set to 0 in case that each ENLOCAL bit of WINCON0 ~ 2 registers is enabled. this issue would be solved with local path feature soon.
