Re: [PATCH 0/3] [media] tvp5150: Migrate to media-controller framework and add video format detection

The tvp5150 video decoder is usually used on a video pipeline with several
video processing integrated circuits. So the driver has to be migrated to
the new media device API to reflect this at the software level.

Also the tvp5150 is able to detect what is the video standard at which
the device is currently operating, so it makes sense to add video format
detection in the driver as well as.

This patch-set migrates the tvp5150 driver to the MCF and adds video format detection.

What is this patchset relative to?
Does it still handle the case of overscan? e.g. I typically capture from
an NTSC source using this device at 720x524.
Even if it does detect the signal shape (NTSC, PAL), doesn't one still need
to [externally] configure the pads for this shape?

Have you given any thought as to how the input (composite-A, composite-B or S-Video)
could be configured using the MCF?
