Hmm, 'BA12' clashes with V4L2_PIX_FMT_SGRBG12 which has the same fourcc.
That fourcc makes no sense for V4L2_PIX_FMT_SGRBG12 and I suspect it was
a mistake, but it's been in use since 2014.
I think V4L2_PIX_FMT_BGRA444 should get a different fourcc and be backported to 5.2.
Can you address this issue?
Regards,
Hans
