      drm/i915: Ignore long hpds on eDP ports · 7a7f84cc
      Ville Syrjälä 提交于
      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.

      drm/i915: Do a dummy DPCD read before the actual read · f6a19066
      Ville Syrjälä 提交于
      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.

      ARM: dts: imx28-evk: Let i2c0 run at 100kHz · d1e61eb4
      Fabio Estevam 提交于
      Commit 78b81f46 ("ARM: dts: imx28-evk: Run I2C0 at 400kHz") caused issues
      when doing the following sequence in loop:
      
      - Boot the kernel
      - Perform audio playback
      - Reboot the system via 'reboot' command
      
      In many times the audio card cannot be probed, which causes playback to fail.
      
      After restoring to the original i2c0 frequency of 100kHz there is no such
      problem anymore.
      
      This reverts commit 78b81f46.
