[Intel-gfx] [PATCH] drm: HDMI pixel replication modes now hactive of 720 for pixel replication

Tue Jul 29 23:58:23 CEST 2014
From: Clint Taylor <clinton.a.taylor at intel.com>
CEA SD interlaced modes use a horizontal 720 pixels that are pixel replicated to 1440. The current driver reports 1440 pixel to the OS and does not set pixel replicated modes.
