[PATCH v2 09/23] ARM: OMAP: AM3517evm: Adapt to ehci-omap changes

Roger Quadros rogerq at ti.com
Sat Mar 16 02:16:30 EST 2013


Add 2 platform devices for 'nop-usb-xceiv'. These will be used as a
PHY for HS USB Port 1 and 2, so provide binding information for them.

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