   3 Required properties for dp-controller:
   4         -compatible:
   5                 platform specific such as:
   6                  * "samsung,exynos5-dp"

   8         -reg:
   9                 physical base address of the controller and length
  10                 of memory mapped region.
  11         -interrupts:
  12                 interrupt combiner values.
  13         -clocks:
  14                 from common clock binding: handle to dp clock.
  15         -clock-names:
  16                 from common clock binding: Shall be "dp".
  17         -interrupt-parent:
  18                 phandle to Interrupt combiner node.

  26                 Indicate driver need force hpd when hpd detect failed, this
  27                 is used for some eDP screen which don't have hpd signal.
  28         -hpd-gpios:
  29                 Hotplug detect GPIO.
  30                 Indicates which GPIO should be used for hotplug detection
  31         -port@[X]: SoC specific port nodes with endpoint definitions as defined
  32                 in Documentation/devicetree/bindings/media/video-interfaces.txt,
  33                 please refer to the SoC specific binding document:
