From 01984da4f7009c118c18fa251b703de74f26ced2 Mon Sep 17 00:00:00 2001

Subject: [PATCH] ARM: OMAP3: Fix EHCI initialization for Overo
Overo uses port 2, not port 1. Use OVERO_GPIO_USBH_NRESET rather than hard coded value
Note: this alone will not give functional EHCI. Also required is:
[PATCH 4/9] ehci: fix phy_reset init in ehci probe
