      drm/edid: Allow HDMI infoframe without VIC or S3D · f1781e9b
      Ville Syrjälä authored
      Appedix F of HDMI 2.0 says that some HDMI sink may fail to switch from
      3D to 2D mode in a timely fashion if the source simply stops sending the
      HDMI infoframe. The suggested workaround is to keep sending the
      infoframe even when strictly not necessary (ie. no VIC and no S3D).
      HDMI 1.4 does allow for this behaviour, stating that sending the
      infoframe is optional in this case.
      
      The infoframe was first specified in HDMI 1.4, so in theory sinks
      predating that may not appreciate us sending an uknown infoframe
      their way. To avoid regressions let's try to determine if the sink
      supports the infoframe or not. Unfortunately there's no direct way
      to do that, so instead we'll just check if we managed to parse any
      HDMI 1.4 4k or stereo modes from the EDID, and if so we assume the
      sink will accept the infoframe. Also if the EDID contains the HDMI
      2.0 HDMI Forum VSDB we can assume the sink is prepared to receive
      the infoframe.
      
      v2: Fix getting has_hdmi_infoframe from display_info
          Always fail constructing the infoframe if the display
          possibly can't handle it

      video/hdmi: Allow "empty" HDMI infoframes · 593f4b19
      Ville Syrjälä authored
      HDMI 2.0 Appendix F suggest that we should keep sending the infoframe
      when switching from 3D to 2D mode, even if the infoframe isn't strictly
      necessary (ie. not needed to transmit the VIC or stereo information).
      This is a workaround against some sinks that fail to realize that they
      should switch from 3D to 2D mode when the source stop transmitting
      the infoframe.
      
      v2: Handle unpack() as well
          Pull the length calculation into a helper
