They correspond to the V4L2 10- and 12-bit greyscale (V4L2_PIX_FMT_Y10 and V4L2_PIX_FMT_Y12) formats, as well as the Bayer formats with the same bit depth (V4L2_PIX_FMT_SBGGR{10,12} and all other Bayer pattern permutations). These formats are not used by any kernel driver at this point, but need to be exposed to applications by libcamera, which uses DRM FourCCs for pixel formats.
