Documentation
On some devices the LCD panel is mounted in the casing in such a way
that the up/top side of the panel does not match with the top side of
the device. Userspace can use this property to check for this.
Note that input coordinates from touchscreens (input devices with
INPUT_PROP_DIRECT) will still map 1:1 to the actual LCD panel
coordinates, so if userspace rotates the picture to adjust for
the orientation it must also apply the same transformation to the
touchscreen input coordinates. This property is initialized by calling
drm_connector_set_panel_orientation() or
drm_connector_set_panel_orientation_with_quirk()
