The banana Pi was delivered with several different RGB LCD modules.
3.5" (Bpi LCD 1003)
This is a 3.5" RGB TFT display with 320x240 resolution.
This happens to be the displays used in the FOSDEM video boxes, and PaulK has kindly made this work.
While these are destined for upstream, PaulK is currently tracking the relevant patches on his own personal repo in the bananapi-lcd-3.5 branch.
