From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx> Here's a respin of my DP++ adaptor support series [1]. Pardon for taking forever with this. Presumably we want to get this into stable to fix the regression from HDMI 12bpc support. I've tried to account for a bunch of Paulo's review comments I also tried to make the helper a bit easier to use by having the caller pass the adaptor type to the helper functions, and so the need for most adaptor type checks in driver code is eliminated. I still left some checks in i915, but those are there just to do the type 1 DVI vs. none detectio, and to suppress the debug output when no adaptor is detected. I also redid the detection logic a bit to ease future LSPCON enabling. I had to rebase a bunch of stuff due to VBT shuffling. I also noticed that my BSW still wasn't detecting type 1 DVI adaptors, which I managed to "fix" by having the VBT check also accept HDMI type dvo_ports as DP++ ports, which sucks a bit but should hopefully be robust enough. I felt that things changed a bit too much in the end for me to hang on to the r-bs unfortunately, so I didn't actually pick them up. So if people aren't too fed up with this, I'd appreciate them having a a second look.
