[PATCH v2 13/23] ARM: OMAP3: igep0020: Adapt to ehci-omap changes

Roger Quadros rogerq at ti.com
Sat Mar 16 02:16:34 EST 2013


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

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