[PATCH r128] Improve handling of monitor and output types

Connor Behan connor.behan at gmail.com
Mon Aug 4 15:32:42 PDT 2014


Checking for OUTPUT_DVI is not the same as checking for MT_DFP. There
might be r128 cards with a DVI-I connector. These have the capability of
driving an MT_CRT so we now check the monitor type before programming
DAC or TMDS registers.

This patch also removes R128ConnectorType and R128BIOSConnector because
they were not doing much. These data structures are more useful for the
radeon driver where there is a much wider range of cards.
