[Intel-gfx] [PATCH 0/8] fdi link auto-dither

[Daniel Vetter]

Hi all,

So these patches finally use the new pipe_config infrastructure to beat our fdi
link handling on ivb (especially for 3 pipe configs) really into shape.

This also adds hw state readout support so that fastboot handles this all
correctly, too.

Unfortunately there's no 6bpc support for the LPT PCH at all, so we can't pull
off the same clever tricks on Haswell. This is the big change compared to the
previous submission, I've forgotten all about this. Currently we can't even
display a 1080p resolution on VGA, but Paulo will resurrect some patches to
ditch the fdi ssc safety margin.

Cheers, Daniel
