drm/i915: parse child device from VBT
On some laptops there is no HDMI/DP. But the xrandr still reports several disconnected HDMI/display ports. In such case the user will be confused. >DVI1 disconnected (normal left inverted right x axis y axis) >DP1 disconnected (normal left inverted right x axis y axis) >DVI2 disconnected (normal left inverted right x axis y axis) >DP2 disconnected (normal left inverted right x axis y axis) >DP3 disconnected (normal left inverted right x axis y axis) This patch set is to use the child device parsed in VBT to decide whether the HDMI/DP/LVDS/TV should be initialized. Parse the child device from VBT. The device class type is also added for LFP, TV, HDMI, DP output. https://bugs.freedesktop.org/show_bug.cgi?id=22785 Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Reviewed-by: Adam Jackson <ajax@redhat.com> Signed-off-by: Eric Anholt <eric@anholt.net>
