I tested these with DRA76 EVM & CAL, using CAL's legacy non-MC mode. It doesn't work. I think there are two problems:
- CAL uses mbus codes like MEDIA_BUS_FMT_UYVY8_2X8 for CSI-2, not 1X16. OV5640 used to support 2X8, but now it doesn't.
- OV5640 sets the default code to MEDIA_BUS_FMT_UYVY8_2X8, even for CSI-2 where it doesn't support MEDIA_BUS_FMT_UYVY8_2X8.
I'd like to just change CAL and drop the 2X8 support and instead use 1X16, but then any sensor that uses 2X8 would work. So I guess I need to change the code to support both.
Anyway, both of those issues might also surface on other platforms, as ov5640 behavior has changed.
