[PATCH v2 0/3] drm/mgag200: Detect connector status

[Thomas Zimmermann]

Detect the connector status by polling the DDC. Update the status at
runtime. Add a dedicated BMC output to still display to the BMC while
the VGA connector is not attached.

This patchset fixes a long-standing problem where attaching the VGA
display a runtime resulted in incorrect display modes.

Tested on various Matrox hardware.

v2:
- move the DDC clean up into a separate patchset [1]
- add dedicated BMC support (Jocelyn)
