On 6328, the same register space allows the controlling of the USB PHY
in either host or device mode, so I believe you would need to add a
#phy-cells = 1 in order to distinguish the consumer (host versus device)
if we get to the point where drivers/usb/gadget/udc/bcm63xx_udc.c
becomes DT aware.

Other than that, this looks good to me!
