The USB5807 is a 7-port USB 3.1 hub that can be configured by I2C.
This driver resets the chip, optionally allows D+/D- lines to be
swapped in the devicetree config, and then sends an ATTACH command to
put the device in operational mode.

Changes in v3:
Add minItems

Changes in v2:
Rename to microchip,usb5807.yaml

My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
on your patch (DT_CHECKER_FLAGS is new in v5.13):

yamllint warnings/errors:

dtschema/dtc warnings/errors:
/builds/robherring/dt-review-ci/linux/Documentation/devicetree/bindings/usb/usb251xb.example.dtb: usb-hub@2d: swap-dx-lanes: size is 32, expected 8
	From schema: /builds/robherring/dt-review-ci/linux/Documentation/devicetree/bindings/usb/usb251xb.yaml

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20230522074510.16367-1-mike.looijmans@topic.nl

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.
