drm/i915: Extract physical display dimensions from VBT
The VBT has these mysterious H/V image sizes as part of the display timings. Looking at some dumps those appear to be the physical dimensions in mm. Which makes sense since the timing descriptor matches the format used by EDID detailed timing descriptor, which defines these as "H/V Addressable Video Image Size in mm". So let's use that information from the panel fixed mode to get the physical dimensions for LVDS/eDP/DSI displays. And with that we can fill out the display_info so that userspace can get at it via GetConnector. v2: Use (hi<<8)|lo instead of broken (hi<<4)+lo Handle LVDS and eDP too Cc: Stephen Just <stephenjust@gmail.com> Tested-by: Stephen Just <stephenjust@gmail.com> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=96255 Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1464685714-30507-1-git-send-email-ville.syrjala@linux.intel.com Reviewed-by: Mika Kahola <mika.kahola@intel.com> (cherry picked from commit df457245b5b7515cf97763ebd8975229e34d4cf3) Signed-off-by: Jani Nikula <jani.nikula@intel.com>
