Hi Dave,

Please do _not_ pull this. The pipe bpp readout stuff this crucially relies on is only partially backported from -next to -fixes and apparently missing bits on Haswell.

Ok, updated pull request. I wanted to wait a bit for an ivb 3 pipe regression fix, but my brain was too fuzzy thus far to write a correct patch ... So I guess that one will go through the merge window with a cc: stable.

On top of the edp bpp fix from Jani just a no-lvds quirk. The two patches from Ville are both from -next and provide infrastructure for Jani's fix. I could have done a more minimal port, but I'd like to avoid divergent code for backports as much as possible.

Cheers, Daniel

Hi Dave,

Just the edp bpp fix from Jani plus the pipe bpp readout code from Ville to make it work. There's a 3 pipe ivb regression fix pending from me, but Ville's review convinced me that my first stab is broken.
