Subject: [PATCH 0/3] media: vimc: Add support for GBR and BGR formats on source pad of debayer

The objective of this series is to add support for GBR and BGR media bus formats
for the source pad of debayer subdevices of the vimc driver.

Since the GBR media bus code doesn't have a corresponding pixelformat, it needed
to use the pixelformat of another bus code.

The first patch makes it possible to have multiple media bus codes mapping to
the same pixelformat.

The second patch adds the GBR media bus code, using the RGB pixelformat.

The third patch adds support for GBR and BGR media bus formats on the source
pad of the debayer subdevice.

This patch series passed all tests of v4l2-compliance:
$ compliance_git -m /dev/media0
v4l2-compliance SHA: c4a62f26c5c3ecd856ca10cf2f0d35d100283d7f, 64 bits, 64-bit time_t

Grand Total for vimc device /dev/media0: 461, Succeeded: 461, Failed: 0, Warnings: 0

Nícolas F. R. A. Prado (3):
  media: vimc: Support multiple buscodes for each pixelformat
  media: vimc: Add GBR media bus code
  media: vimc: deb: Add support for GBR and BGR bus formats on source
    pad
