I have tested this patch with the following script:
https://github.com/initBasti/Linux_kernel_media_tree_fork/commit/efc4b399cff53fb36fadde999594961a3d84073e
The results on my NanoPC-T4 (Linux nanopct4 5.10.0-rc6-rockchip64):
pad 0 = RKISP1_ISP_PAD_SINK_VIDEO
pad 1 = RKISP1_ISP_PAD_SINK_PARAMS
pad 2 = RKISP1_ISP_PAD_SOURCE_VIDEO
pad 3 = RKISP1_ISP_PAD_SOURCE_STATS

Could you please also run v4l2-compliance ?
Yes, it finished without errors here is the output.

Can't you use function rkisp1_isp_mbus_info_get() ?
Check how rkisp1_isp_set_src_fmt() checks for a valid mbus code.
Thanks
