This series convert cdn-dp-rockchip.txt to yaml.

PATCH 1 try to improve coding style on the existing rk3399 cdn-dp
node.
PATCH 2 try to convert cdn-dp-rockchip.txt to yaml.

Tested with:

1. make ARCH=arm64 dt_binding_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/display/rockchip/rockchip,cdn-dp.yaml

2. make ARCH=arm64 dtbs_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/display/rockchip/rockchip,cdn-dp.yaml

Let's make the ports nodes of cdn_dp in the same style as the other
display interface, and match the style of ports's yaml.

-Rockchip RK3399 specific extensions to the cdn Display Port
-================================
-
-Required properties:
-- compatible: must be "rockchip,rk3399-cdn-dp"
-
-- reg: physical base address of the controller and length
-
-- clocks: from common clock binding: handle to dp clock.
-
-- clock-names: from common clock binding:
-	       Required elements: "core-clk" "pclk" "spdif" "grf"
-
-- resets : a list of phandle + reset specifier pairs
-- reset-names : string of reset names
-		Required elements: "apb", "core", "dptx", "spdif"
-- power-domains : power-domain property defined with a phandle
-		  to respective power domain.
-- assigned-clocks: main clock, should be <&cru SCLK_DP_CORE>
-- assigned-clock-rates : the DP core clk frequency, shall be: 100000000
-
-- rockchip,grf: this soc should set GRF regs, so need get grf here.
-
-- ports: contain a port nodes with endpoint definitions as defined in
-	 Documentation/devicetree/bindings/media/video-interfaces.txt.
-	 contained 2 endpoints, connecting to the output of vop.
-
-- phys: from general PHY binding: the phandle for the PHY device.
-
-- extcon: extcon specifier for the Power Delivery
-
-- #sound-dai-cells = it must be 1 if your system is using 2 DAIs: I2S, SPDIF

My bot found errors running 'make dt_binding_check' on your patch:

yamllint warnings/errors:

dtschema/dtc warnings/errors:


doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20250508064304.670-3-kernel@airkyi.com

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.

Drop. You do not have to embed in commit msg standard makefile targets.
We all know how to use it. You do not do it for C files, do you?

Missing constraints. Drop description.

Just look at other bindings.

Drop these two

Missing type, unless you could not add a type because of conflicts? This
should be really fixed...

and here is maxItems. Why in other places you put minItems?

Why is this flexible? It wasn't in original binding and you must
document all the changes done to the binding in commit msg.
