From 54a419668b0f27b7982807fb2376d237e0a0ce05 Mon Sep 17 00:00:00 2001
From: Alan Stern <stern@rowland.harvard.edu>
Date: Tue, 12 Mar 2013 10:44:39 +0000
Subject: USB: EHCI: split ehci-omap out to a separate driver
This patch (as1645) converts ehci-omap over to the new "ehci-hcd is a
library" approach, so that it can coexist peacefully with other EHCI
platform drivers and can make use of the private area allocated at
the end of struct ehci_hcd.
