Hi guys,

One version more with fixes.

Changes since v3:
- Fixes to iMX code from Sascha Hauer

Quick summary:
This introduces struct usb_phy and struct usb_otg that
replace struct otg_transceiver. The transceiver and phy
members from struct otg_transceiver are left in struct
usb_phy and otg specific members are moved to struct
usb_otg.

So the idea is simply to separate USB PHY handling from OTG.


Heikki Krogerus (19):
  usb: otg: Rename otg_transceiver to usb_phy
  usb: otg: Rename usb_otg and usb_xceiv to usb_phy
  usb: otg: Separate otg members from usb_phy
  usb: otg: ab8500: Start using struct usb_otg
  usb: otg: fsl: Start using struct usb_otg
  usb: otg: gpio_vbus: Start using struct usb_otg
  usb: otg: isp1301_omap: Start using struct usb_otg
  usb: otg: msm: Start using struct usb_otg
  usb: otg: langwell: Start using struct usb_otg
  usb: otg: nop: Start using struct usb_otg
  usb: otg: twl4030: Start using struct usb_otg
  usb: otg: twl6030: Start using struct usb_otg
  usb: otg: ulpi: Start using struct usb_otg
  arm: imx: Start using struct usb_otg
  usb: musb: Start using struct usb_otg
  power_supply: Convert all users to new usb_phy
  usb: Convert all users to new usb_phy
  usb: otg: Remove OTG specific members from usb_phy
  usb: otg: Convert all users to pass struct usb_otg for OTG functions

Introducing struct otg and collecting otg specific members
to it from struct usb_phy. There are no changes to
struct usb_phy at this stage. This also renames
transceiver specific functions, and offers aliases for the
old otg ones.

All the drivers are now converted to use struct usb_otg, so
removing the OTG specific members from struct usb_phy.

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.

Adding Philippe who has access to the mx31moboard-devboard and maybe
could run a test?

Linus's tree. It's possible that our smtp server has done something it
should not have. If this is the case, you will find this patch set here:

git://github.com/krohei/linux.git branch otg

Tested on mx31moboard-marxbot, works fine (ie, nothing changed).

BTW, totally unrelated, but I had to disable the sdma in order to boot

the dma now.
