Does not look like you tested the DTS against bindings. Please run `make dtbs_check` (see Documentation/devicetree/bindings/writing-schema.rst for instructions).
... because it does not really make sense. Why do you require SD6HC as fallback? I think you meant enum.

No underscores. Use proper units in name suffix: https://github.com/devicetree-org/dt-schema/blob/main/dtschema/schemas/property-units.yaml

Ditto... and so on - all of the fields.

Why these three are properties of DT?

This is confusing. I don't understand it. It requires much more explanation in your commit msg.
