>From 8081a7f7b74310d9cfd03637741d59d8fd66d1e5 Mon Sep 17 00:00:00 2001 From: Alex Deucher <alexdeuc...@gmail.com> Date: Wed, 17 Mar 2010 19:50:59 -0400 Subject: [PATCH] drm/radeon/kms: remove lvds quirks
- no longer needed with the latest new pll algo fixes.
- also don't use lcd pll limits. They don't seem
to work well for all systems. If we have a case where
they are useful, we can set the flag for that case.
fixes fdo bug 27083
