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.
I think that is genuinely something we should handle in camss-csid.c
maybe with some meta-data inside of the ports/endpoints..
This is a CSIPHY property, a CSIPHY hardware configuration and a wiring
of sensors to a CSIPHY. Where is the relation to CSID here? There is no.

Please share at least a device tree node description, which supports
a connection of two sensors to a single CSIPHY, like it shall be done
expectedly.
