Raydium RM69380 is a display driver IC used to drive OLED DSI panels.
Add a dt-binding for it.

You have only one variant, so entire if: is not needed. Just require
ports in top-level, if you say this device cannot support single-link
(just to remind: we talk about what device supports, not driver).

Redundant, drop.

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

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20240414-raydium-rm69380-driver-v1-1-5e86ba2490b5@mainlining.org

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.
