[v3,1/5] dt-bindings: phy: imx8mq-usb: add compatible "fsl,imx95-usb-phy"

Commit Message

The usb phy in i.MX95 is compatible with i.MX8MP's, this will add a
compatible "fsl,imx95-usb-phy" for i.MX95. Also change reg maxItems
to 2 since i.MX95 needs another regmap to control Type-C Assist (TCA)
block. Since i.MX95 usb phy is able to switch SS lanes, this will also
add orientation-switch and port property to the file.

Changes in v2:
 - replace minItems with description in reg property
 - remove orientation-switch and port
 - refer to usb-switch.yaml
 - use unevaluatedProperties
Changes in v3:
 - add Rb tag
