2014-10-27cpufreq: cpufreq-dt: disable unsupported OPPsLucas Stach
If the regulator connected to the CPU voltage plane doesn't support an OPP specified voltage with the acceptable tolerance it's better to just disable the OPP instead of constantly failing the voltage scaling later on. Includes a fix to move initialization of opp_freq outside the loop to avoid an endless loop from Geert Uytterhoeven.

2014-10-27drm/i915: Ignore long hpds on eDP portsVille Syrjälä
Turning vdd on/off can generate a long hpd pulse on eDP ports. In order to handle hpd we would need to turn on vdd to perform aux transfers. This would lead to an endless cycle of "vdd off -> long hpd -> vdd on -> detect -> vdd off -> ..." So ignore long hpd pulses on eDP ports. eDP panels should be physically tied to the machine anyway so they should not actually disappear and thus don't need long hpd handling. Short hpds are still needed for link re-train and whatnot so we can't just turn off the hpd interrupt entirely for eDP ports. Perhaps we could turn it off whenever the panel is disabled, but just ignoring the long hpd seems sufficient.

2014-10-27drm/i915: Do a dummy DPCD read before the actual readVille Syrjälä
Sometimes we seem to get utter garbage from DPCD reads. The resulting buffer is filled with the same byte, and the operation completed without errors. My HP ZR24w monitor seems particularly susceptible to this problem once it's gone into a sleep mode. The issue seems to happen only for the first AUX message that wakes the sink up. But as the first AUX read we often do is the DPCD receiver cap it does wreak a bit of havoc with subsequent link training etc. when the receiver cap bw/lane/etc. information is garbage. A sufficient workaround seems to be to perform a single byte dummy read before reading the actual data. I suppose that just wakes up the sink sufficiently and we can just throw away the returned data in case it's crap. DP_DPCD_REV seems like a sufficiently safe location to read here.
