Subject: Correct place for USB PHY driver

Hello,

I have a board with a Chipidea controller.
I use a custom PHY driver for it.

Should the PHY driver live in drivers/phy or in drivers/usb/phy ?

I was playing with a modular build and hit this problem:
ERROR: "of_usb_get_phy_mode" [drivers/usb/chipidea/ci_hdrc.ko] undefined!

I'm currently using v4.1.13 and I saw that Arnd fixed something related
probably in a later version:

  http://thread.gmane.org/gmane.linux.ports.arm.kernel/457561

Was this patch accepted upstream?

Regards.
