[PATCH] drm/i915: honor forced connector modes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



In the move over to use BIOS connector configs, we lost the ability to
force a specific set of connectors on or off.  Try to remedy that by
dropping back to the old behavior if we detect a hard coded connector
config.
