[PATCH v2 19/23] ARM: OMAP: zoom: Adapt to ehci-omap changes

Roger Quadros rogerq at ti.com
Sat Mar 16 02:16:40 EST 2013


Add platform device for 'nop-usb-xceiv'. This will be used as a
PHY for HS USB Port 2, so provide binding information for it.

Use usbhs_init_phys() to register the PHY's RESET regulator.
