Maxime gave[1] a good overview of the situation with these displays and proposed to make a driver that works with all MIPI DBI compatible controllers and use a firmware file to provide the controller setup for a particular panel. Changes since version 3: - There should only be two compatible (Maxime) - s/panel-dbi-spi/panel-mipi-dbi-spi/in compatible - Move driver to drm/tiny where the other drivers of its kind are located. The driver module will not be shared with a future DPI driver after all. See wiki[2] for script to make command firmware files. Noralf.
