Subject: OMAPDSS: Add interlace parameter to omap_video_timings
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=23c8f88e8a140c8435658c369b26c7b60d8fe3c0;p=~shefty%2Frdma-dev.git

OMAPDSS: Add interlace parameter to omap_video_timings

Add a parameter called interlace which tells whether the timings are in
interlaced or progressive mode. This aligns the omap_video_timings struct with
the Xorg modeline configuration.

It also removes the hack needed to write to divide the manager height by 2 if
the connected interface is VENC.
