The display sysfs file for viewing/storing display timings is something which
will be deprecated. The new omap_video_timings fields (hsync_level, vsync_level
and others) are not configurable or viewable via this sysfs file.
This prevents the need to make the input more configurable to take the new
fields and at the same time work without these fields for backward
compatibility.
In display_timings_store, the omap_video_timings struct used to set the timings
is initialized to the existing panel timings so that the new fields are taken in
correctly. The other fields are taken from the user as before.
