I assume the mode of operation (input or output) will be fixed for a
given hardware design. Isn't this something that should be recorded in
DT ? It would simplify configuration of the device in the driver.

Currently the configuration (DSI-to-DPI / DPI-to-eDP) is inferred from the presence of DPI panel. If DPI panel present, DSI-to-DPI, else, DPI-to-eDP.
