Try to deal with duplicate child devices for the same DDI port by attempting to initialize them in VBT defined order The first on to succeed for a specific DDI port will be the one we use. We'll also get rid of i915->display.vbt.ports[] here as any conflicts will now be handled at encoder registration time rather than during VBT parsing. Note that intel_bios_encoder_data_lookup() still remaims for pre-DDI DP/HDMI ports as those don't (at least yet) use VBT driven initialization. TODO: DSI dual link handling is sketchy at best v2: Leave intel_bios_encoder_port() to the encoder callback (Jani) Cc: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230630155846.29931-7-ville.syrjala@linux.intel.com Reviewed-by: Jani Nikula <jani.nikula@intel.com>
