Above information is based on the presentations by Dave Anders available here: http://elinux.org/Elc-lcd This patch adds the parallel TFT display type and basic parameters structure. Maybe it should be split into a separate header, eg. include/video/tft.h? Or maybe it's just the INTERFACE_DPI I'm talking about?
