Sorry for chiming in very late, but can you please provide on which
i.MX9 devices this formatting module is present? I've checked the i.MX93
reference manual and found no info instead I found a CAMERA_MUX register
which does something similiar but is not the same. Please provide a more
specific compatible if this IP is only be present on i.MX95 devices.

Regards,
  Marco
