The goal of this series is to let userland applications enumerate
all the supported pixels formats of a stateless decoder without
setting all the possible codec-dependent control.
That offer a simplest solution for applications to discover
supported pixels formats and possibly let them doing smarter
choice between stateless decoders.

changes in version 2:
- Clarify documentation.
- Only keep V4L2_FMT_FLAG_ALL_FORMATS flag in ioctl.

  media: videodev2: Add V4L2_FMT_FLAG_ALL_FORMATS flag
