From 2aae4221eebf926ad1058546e2cb81dae8f3e696 Mon Sep 17 00:00:00 2001 From: Anand Gadiyar Date: Wed, 16 Feb 2011 15:42:15 +0530 Subject: arm: omap4: usb: explicitly configure MUSB pads Use the mux framework APIs to explicitly configure the MUSB pads. The MUSB controller in OMAP4 can use either the old ULPI interface, or the new internal PHY. Configure the pads accordingly.
