drm: read EDID extensions from monitor
Usually drm read basic EDID, that is enough for us, but since igital display were introduced i.e. HDMI monitor, sometime we need to interact with monitor by EDID extension information, EDID extensions include audio/video data block, speaker allocation and vendor specific data blocks. This patch intends to read EDID extensions from digital monitor for users. Signed-off-by: Ma Ling <ling.ma@intel.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
