One question here: If the PHY "driver" API changes, there will need to be a bunch of ehci-tegra.c changes too. Will you take all those through the PHY tree? If you expect to do that, then I'd like to request you also take:
usb: host: tegra remove include of <mach/iomap.h> http://www.spinics.net/lists/linux-usb/msg72429.html
... since that should get merged before any large changes to ehci-tegra.c; it's the EHCI equivalent of the PHY patch you already merged.
(The same request applies to put that into a branch I can pull into the Tegra tree as a basis for cleanup in the Tegra tree)
Thanks!
