[RFC,4/4] dt-binding: clock: hisilicon,clock-reset-controller: add Hi3798MV200 SoC support
Commit Message
From: Yang Xiwen <forbidden405@outlook.com>
This SoC is similar to Hi3798CV200.
Also document the specific DLL regs and add an example for it.

My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20240216-clk-mv200-v1-4-a29ace29e636@outlook.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.

No child nodes, not a simple-mfd.

I imagine you are linking to this node from the SD host controller node
with some custom property. Instead of defining the register address
here, link to the parent node (&crg) instead and make the offset the 2nd
cell.
