you could just make tegra_usb_phy_init() be called as u_phy->init().
That way you even delay enabling clocks and regulators to the point
where they are more likely to be needed. Also, if EHCI is never loaded,
you won't power up the PHY for no reason.

I suppose this has no dependencies with the rest of the series ?
