Subject: [PATCH 00/16] Switch subdev dv timing callbacks to pad ops

Currently, subdev dv timing calls (i.e. g/s/query_dv_timings) are video
ops without a pad argument. This is a problem if the subdevice can have
different dv timings for each pad (e.g. a DisplayPort receiver with
multiple virtual channels).

This patchset changes subdev dv timing callbacks to include a pad
argument, and moves them from video to pad ops. All the affected
drivers are updated to use the new pad ops version.

The affected drivers were updated in a way that mathes how they deal
with the pad argument in other callbacks (mainly enum_dv_timings,
dv_timings_cap, get/set_edid).

This was originally a part of a larger patchset:
