    +Rockchip RK3288 specific extensions to the Analogix Display Port
    +================================
    +
    +Required properties:
    +- compatible: "rockchip,rk3288-edp";
    +
    +- reg: physical base address of the controller and length
    +
    +- clocks: from common clock binding: handle to dp clock.
    + of memory mapped region.
    +
    +- clock-names: from common clock binding:
    + Required elements: "dp" "pclk"
    +
    +- resets: Must contain an entry for each entry in reset-names.
    + See ../reset/reset.txt for details.
    +
    +- pinctrl-names: Names corresponding to the chip hotplug pinctrl states.
    +- pinctrl-0: pin-control mode. should be <&edp_hpd>
    +
    +- reset-names: Must include the name "dp"
    +
    +- rockchip,grf: this soc should set GRF regs, so need get grf here.
    +
    +- ports: there are 2 port nodes with endpoint definitions as defined in
    + Documentation/devicetree/bindings/media/video-interfaces.txt.
    + Port 0: contained 2 endpoints, connecting to the ouput of vop.
    + Port 1: contained 1 endpoint, connecting to the input of panel.
    +
    +For the below properties, please refer to Analogix DP binding document:
    + * Documentation/devicetree/bindings/drm/bridge/analogix_dp.txt
    +- phys (required)
    +- phy-names (required)
    +- hpd-gpios (optional)
