Lad, Prabhakar e933c6bc67 [media] media: davinci: vpif_display: embed video_device struct in channel_obj
Embed video_device struct (video_dev) in channel_obj and also the
Unregister path doesn't need to free the video_device structure,
hence, change the video_device.release callback point to
video_device_release_empty.

by core.

Lad, Prabhakar 4b8a531e6b [media] media: davinci: vpif: display: add V4L2-async support
Add support for asynchronous subdevice probing, using the v4l2-async API.
The legacy synchronous mode is still supported too, which allows to
gradually update drivers and platforms.

Hans Verkuil 882084ad0f [media] vpif_display: use a v4l2_subdev pointer to call a subdev
This makes it easier to have outputs without subdevs.
This needs more work. The way the outputs are configured should be identical
to how inputs are configured.

Mauro Carvalho Chehab 2c3fb08b3f [media] rename drivers/media/video as .../platform
The remaining drivers are mostly platform drivers. Name the
dir to reflect it.

It makes sense to latter break it into a few other dirs.
