I understand and agree.

On i.MX8M we currently use the usb-nop-xceiv. I guess it's not an option
to just add these properties there, so we'll need a phy node with a new
compatible like fsl,imx8mm-usbphy. The driver would basically just
register a usb-nop-xceiv and the node would be a container for the new
property. Does this sound sane?
