The exceptions are the DSI and DPI controllers, which are documented separately.

These three are already included in the list above.

I'll change this. thank you Philipp _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
