currently use half-baked interfaces.
So hopefully I'll be able to follow the discussion and can then try to convert
your findings to the dbi case.

The idea is to abstract the DSI/DBI-2 type of transport and focus on the DCS command set level. The driver should be able to select between DBI and DSI by providing some "struct dcs_device { ifc = DSI/DBI2, ... }" data to the DCS bus.
Something like a stripped version of www.igloocommunity.org/gitweb/?p=kernel/igloo-kernel.git;a=blob;f=include/video/mcde.h#l113, but for DBI/DSI only.
