Analogix Display Port bridge bindings

Required properties for dp-controller:

	-compatible:

		platform specific such as:

		 * "samsung,exynos5-dp"

		 * "rockchip,rk3288-dp"

		 * "rockchip,rk3399-edp"

	-reg:

		physical base address of the controller and length

		of memory mapped region.

	-interrupts:

		interrupt combiner values.

	-clocks:

		from common clock binding: handle to dp clock.

	-clock-names:

		from common clock binding: Shall be "dp".

	-phys:

		from general PHY binding: the phandle for the PHY device.

	-phy-names:

		from general PHY binding: Should be "dp".

Optional properties for dp-controller:

	-force-hpd:

		Indicate driver need force hpd when hpd detect failed, this

		is used for some eDP screen which don't have hpd signal.

	-hpd-gpios:

		Hotplug detect GPIO.

		Indicates which GPIO should be used for hotplug detection

	-port@[X]: SoC specific port nodes with endpoint definitions as defined

		in Documentation/devicetree/bindings/media/video-interfaces.txt,

		please refer to the SoC specific binding document:

		* Documentation/devicetree/bindings/display/exynos/exynos_dp.txt

		* Documentation/devicetree/bindings/display/rockchip/analogix_dp-rockchip.txt
