So DSI is more like i2c than the DisplayPort aux channel or DDC. That
seems fine; you can create a DSI infrastructure like the i2c
infrastructure and then just have your display drivers use it to talk to
the panel. We might eventually end up with some shared DRM code to deal
with common DSI functions for display devices, like the EDID code
today, but that doesn't need to happen before you can write your first
DSI-using display driver.
