-Rockchip RK3288 specific extensions to the Analogix Display Port
-================================
-
-Required properties:
-- compatible: "rockchip,rk3288-dp",
- "rockchip,rk3399-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 output of vop.
- Port 1: contained 1 endpoint, connecting to the input of panel.
-
-Optional property for different chips:
-- clocks: from common clock binding: handle to grf_vio clock.
-
-- clock-names: from common clock binding:
- Required elements: "grf"
-
-For the below properties, please refer to Analogix DP binding document:
- * Documentation/devicetree/bindings/display/bridge/analogix_dp.txt
-- phys (required)
-- phy-names (required)
-- hpd-gpios (optional)
-- force-hpd (optional)
