I believe there is very little room to disagree...

This proposed device node scheme does not solve the known and already
discussed technical issue expectedly, namely there is no given way
to describe a combo mode hardware configuration, when two independant
sensors are wired to the same CSIPHY. This is an unsolvable problem
with this design.

Sensors are conneced to CSIPHY IP blocks, CSIPHY is connected to CSID.
