Yes, but this is also used by:

$ git grep "musb-ti81xx"
arch/arm/mach-omap2/usb-musb.c:         name = "musb-ti81xx";
drivers/usb/musb/musb_dsps.c:           .name   = "musb-ti81xx",

Is that one also am33xx?

So keep this is as is and add later a phy_get into musb? I would have
check if everyone has a phy instance but I guess so.
