sys/dev/pci/drm/i915: intel_sdvo.c
Log message:
Resort to I2C bit-banging on the SDVO port like Linux does. Using GMBUS simply
doesn't work reliably. On some machines you can talk to the SDVO chip, but
not to the DDC channel associated with it. On others ou can't even reliably
communicate with the SDVO chip.
Might make all sorts of digital video ports (DVI, HDMI) work. Some systems
need further changes to adjust timings in the I2C bit-banging code.
