I posted a patchset to support nodes not in device tree. And 
Cristian gave some comments:
https://lore.kernel.org/all/Znv1p3FDiPSUNmBM@pluto/

i.MX95 no need dedicated channel for this node, but others may
have. So I repost this patch, and with this binding change,
the dtbs_check could pass for i.MX95 dts.

Thanks,
Peng.
