Hi all,
This series moves s_stream from struct v4l2_subdev_video_ops to struct
v4l2_subdev_pad_ops. The reason for this is that there are devices
(adv7482 for example) which can support more then one video pipeline
connected to two different output pads to run simultaneously. In order
to be able to be able to start and stop streams on a pad level the
s_stream operation needs to be extended with a pad argument.
The series is based on the master branch of the media_tree.
It have been suggested by both Laurent Pinchart and Hans Verkuil that if
a pad aware s_stream is needed the operation should be moved from the
video struct to the pad ops struct and not just add a s_stream to the
pad ops struct.
The change to v4l framework is trivial and only moves s_stream between
the two structs and adds a 'pad' argument. The majority of the changes
is updating all users of the s_stream operation to use the one from
v4l2_subdev_pad_ops.
Patch 1/2 is a preparation of the vsp1 driver where the
v4l2_subdev_video_ops struct was shared by two devices which no longer
can be shared since only one of them implements s_stream.
Patch 2/2 moves the s_stream operation between the struct and updates
all users. The callers have primarily been updated using Coccinelle
patch which is attached to this cover letter.
After the spatch run all changes have been manually reviewed and struct
v4l2_subdev_pad_ops have been added to drivers which previously did not
have one. Likewise struct v4l2_subdev_video_ops which became 'empty'
after removing s_stream have been removed. A few drivers needed some
code to me moved around (most notably s5k4ecgx) for ordering but nothing
in the code itself have changed while moving it except to update calls
to s_stream to use the pad version.
I have tested this series to the best of my ability by building
allyesconfig configurations for arm, arm64 and x86_64. I have also
tested on a R-Car Koelsch board (rcar-vin and adv7180).
