I not understand well about 
" Include interconnects+names in list of all properties ", could you please
explain a bit more?

And there is already an "if" to check whether the
compatible contains " fsl,imx8mp-vpu-blk-ctrl" to make sure the interconnect
valid for i.MX8MP, so it is not valid to other variants.

Thanks,
Peng.
