From 8594ac33450e6d66460230e5d07f5515b51476c9 Mon Sep 17 00:00:00 2001 From: Florian Tobias Schandinat Date: Tue, 22 Sep 2009 16:47:22 -0700 Subject: viafb: remove LVDS initialization At least for VX800 this initialization is not very good as some parts of the register are written with reserved values. This makes the display go white in some configurations and not usable until the framebuffer is removed. It's better to not initialize it as it allows to use a previously (by BIOS) correctly configured display. This patch makes some displays work but might cause problems on others. This is bad but can not be easily avoided. If this causes some regressions it's probably the best to fix it in the 'active' display setup code.
