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 Reviewed-by: Adam Jackson Signed-off-by: Eric Anholt --- Reading git-diff-tree failed
