It is a derived USB PHY and used on most of i.mx chipidea USB controllers.
At the source code, we use aligned id to know the controller number.
ret = of_alias_get_id(np, "usbphy");
if (ret < 0)
dev_dbg(&pdev->dev, "failed to get alias id, errno %d\n", ret);
mxs_phy->port_id = ret;

It is not a new user, the USB PHY used at imx7ulp is the same with imx6's.
Thanks.
