Revision 6f335a7afa6bc57603f39430dc6f9e57de288a91 authored by Ben Skeggs on 29 March 2010, 00:06:09 UTC, committed by Ben Skeggs on 09 April 2010, 00:15:38 UTC 
drm/nv50: preserve an unknown SOR_MODECTRL value for DP encoders
 
This value interacts with some registers we don't currently know how to
program properly ourselves.  The default of 5 that we were using matches
what the VBIOS on early DP cards do, but later ones use 6, which would
cause nouveau to program an incorrect mode on these chips.
