Currently HDMI audio/infoframes is a bit borked on g4x on account
of the hardware only having one audio/video DIP block which can't
be shared among multiple HDMI ports simultanously. Fix that by
selecting exactly one of the enabled HDMI ports for audio/infoframe
transmission.

Ville Syrjälä (5):
  drm/i915: Introduce g4x_hdmi_compute_config()
  drm/i915: Force RGB output for DVI sink
  drm/i915: Treat HDMI as DVI when cloning
  drm/i915: Move has_hdmi_sink out from intel_hdmi_compute_config()
  drm/i915: Pick one HDMI port for infoframe/audio transmission on g4x
