drm/i915: Determine DP++ type 1 DVI adaptor presence based on VBT
DP dual mode type 1 DVI adaptors aren't required to implement any registers, so it's a bit hard to detect them. The best way would be to check the state of the CONFIG1 pin, but we have no way to do that. So as a last resort, check the VBT to see if the HDMI port is in fact a dual mode capable DP port. v2: Deal with VBT code reorganization Deal with DRM_DP_DUAL_MODE_UNKNOWN Reduce DEVICE_TYPE_DP_DUAL_MODE_BITS a bit Accept both DP and HDMI dvo_port in VBT as my BSW at least declare its DP port as HDMI :( v3: Ignore DEVICE_TYPE_NOT_HDMI_OUTPUT (Shashank) Cc: stable@vger.kernel.org Cc: Tore Anderson <tore@fud.no> Reported-by: Tore Anderson <tore@fud.no> Fixes: 7a0baa623446 ("Revert "drm/i915: Disable 12bpc hdmi for now"") Cc: Paulo Zanoni <paulo.r.zanoni@intel.com> Cc: Shashank Sharma <shashank.sharma@intel.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1462362322-31278-1-git-send-email-ville.syrjala@linux.intel.com Reviewed-by: Shashank Sharma <shashank.sharma@intel.com>
