A common property unit suffix '-db' was added to dtschema, thus
in-kernel bindings should not reference the type.

RFC because this depends on dtschema changes and should be accepted
after new dtschema is released with this merged:

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

yamllint warnings/errors:

dtschema/dtc warnings/errors:
/builds/robherring/dt-review-ci/linux/Documentation/devicetree/bindings/phy/fsl,imx8mq-usb-phy.yaml: fsl,phy-pcs-tx-deemph-3p5db-attenuation-db: missing type definition

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20250627-dt-bindings-db-v1-2-d5c7072acbee@linaro.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.

... and I forgot `b4 prep --add-prefixes RFC`. Please treat as RFC.
