Should I do this in > bridge driver one by one? Because various camera hosts (bridges) can produce different pixel formats in memory from the same mediabus code. However, there is a very common way to handle such video data in the bridge: store it in RAM in a "natural" way. This mode is called in soc-camera the pass-through mode and there is an API to handle this mode in drivers/media/video/soc_mediabus.c. If this functionality is considered useful also outside of soc-camera, that API can easily be made generic. > I think these codes are common use, I prefer adding them in > v4l2_fill_pix_format.
