I don't think these formats have originated from MIPI. The colour pattern itself is from Eastman Kodak apparently (named after Bryce Bayer), but the memory format is not, apart from the MIPI CSI-2 packed variant. The formats are probably unlike the formats used on GPUs as they are relatively similar across a number of vendors and devices. There are more raw formats than just the Bayer formats, see e.g. At the same time, it'd be good to keep the CSI-2 packed variant as a format modifier. I wonder if we could have something like DRM_FORMAT_MOD_VENDOR_RAW, albeit a raw format is not a vendor.
