From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx> While fixing up the 12bpc HDMI code I ran afoul of the IBX transcoder B workaround. Turns out that's currently busted. So I fixed it, but that caused the dreaded pipe off timeout to make a reappearance. So to fix that I had to reorganize the crtc disable sequence to actually match the spec (ie. we must disable the pipe before the port). Also I got sick of looking at the mess in the DP code, so I went ahead and cleaned it up a bit. And that also made me notice the CPT/PPT DP enhanced framing mess, which I also tried to fix. So basically I stepped ina another rat's nest again, and had to dig myself out. So far my ILK and IVB seem happy with the result, but I've been able to test all of it (eg. SDVO is untested). The entire series is available here [1] (sitting on top of my HDMI 12bpc series).
