Message-Id: <1319805325-24689-20-git-send-email-heikki.krogerus@linux.intel.com>
Date: Fri, 28 Oct 2011 15:35:25 +0300
From: Heikki Krogerus <heikki.krogerus@...ux.intel.com>
To: Felipe Balbi <balbi@...com>, Greg KH <gregkh@...e.de>

Sascha Hauer <s.hauer@...gutronix.de>
Subject: [PATCHv6 19/19] usb: otg: Convert all users to pass struct usb_otg for OTG functions
This changes the otg functions so that they receive struct
otg instead of struct usb_phy as parameter and
converts all users of these functions to pass the otg member
of their usb_phy.
Includes fixes to IMX code from Sascha Hauer.
