      drm/i915: pass ELD to HDMI/DP audio driver · e0dac65e
      Wu Fengguang authored
      
      
      Add ELD support for Intel Eaglelake, IbexPeak/Ironlake,
      SandyBridge/CougarPoint and IvyBridge/PantherPoint chips.
      
      ELD (EDID-Like Data) describes to the HDMI/DP audio driver the audio
      capabilities of the plugged monitor. It's built and passed to audio
      driver in 2 steps:
      
      (1) at get_modes time, parse EDID and save ELD to drm_connector.eld[]
      
      (2) at mode_set time, write drm_connector.eld[] to the Transcoder's hw
          ELD buffer and set the ELD_valid bit to inform HDMI/DP audio driver
      
      This patch is tested OK on G45/HDMI, IbexPeak/HDMI and IvyBridge/HDMI+DP.
      Test scheme: plug in the HDMI/DP monitor, and run
      
              cat /proc/asound/card0/eld*
      
      to check if the monitor name, HDMI/DP type, etc. show up correctly.
      
      Minor imperfection: the GEN5_AUD_CNTL_ST/DIP_Port_Select field always
      reads 0 (reserved). Without knowing the port number, I worked it around
      by setting the ELD_valid bit for ALL the three ports. It's tested to not
      be a problem, because the audio driver will find invalid ELD data and
      hence rightfully abort, even when it sees the ELD_valid indicator.
      
      Thanks to Zhenyu and Pierre-Louis for a lot of valuable help and testing.

      drm/i915: use GMBUS to manage i2c links · f899fc64
      Chris Wilson authored
      
      
      Use the GMBUS interface rather than direct bit banging to grab the EDID
      over DDC (and for other forms of auxiliary communication with external
      display controllers). The hope is that this method will be much faster
      and more reliable than bit banging for fetching EDIDs from buggy monitors
      or through switches, though we still preserve the bit banging as a
      fallback in case GMBUS fails.
      
      Based on an original patch by Jesse Barnes.
