This patch adds a UDC driver for OMAP, which should work on most
OMAP processors.  It's been tested most on OMAP 1611/5912.  The
driver supports all USB transfer types (including ISO), has limited
DMA support, and seems to work with all gadget drivers, both to
Linux hosts and to MS-Windows ones.

One reason this UDC is particularly interesting is that recent OMAP
processors all support "USB On-The-Go" (OTG) ... and this driver
supports it on at least "H2-like" boards.

Another reason is that the UDC is very flexible and fully featured;
gadget drivers can allocate fifo space to endpoints in the way that's
most convenient for the application.

Greg:

This patch updates the part of the usbtest driver that tests URB
unlinking.  The move to usb_kill_urb() invalidated some of the old tests.
There's a corresponding change to the UHCI driver, causing it to return a
more descriptive error code in the rare event that an URB is cancelled
after it has been linked but before it has been queued.

This adds the isp1301_omap driver, supporting USB OTG on OMAP systems.
The driver tightly couples two different chunks of hardware, which are
used to implement the OTG protocols:

 - The Philips ISP1301 OTG transceiver (an I2C device) senses voltage
   levels and sources VBUS current in the A-Device roles.

 - OMAP's OTG controller handles lots of OTG transitions, and
   tells the transceiver what to do.

The driver implements the abstract "otg_transceiver" API, since it's got to
talk to both the host controller (OHCI on current OMAPs) and the peripheral
controller (omap_udc) while hiding a variety of implementation details.  It
should be easy to tweak to work on other OMAP boards using the isp1301 chip;
OMAP boards with other transceivers, or non-OMAP boards using isp1301, will
probably find things to learn from.

Note that this also supports two non-OTG modes, with the OTG controller
disabled; very handy for debugging just the host side USB stack, or just the
peripheral side USB stack.

This updates the OMAP OHCI support to match the latest from the
Linux-OMAP tree.  Notable changes from the preceding version:

  - Use the new USB init model (arch/arm/mach-omap/usb.c).

  - The OMAP-specific bus is gone; it now uses platform_device.
    (Update from Tony Lindgren.)

  - Works on the H2 board, which requires the external isp1301
    transceiver even in non-OTG configurations.

  - Adds OTG support.

  - Adds basic power management calls.

The mach-omap/Kconfig file in the main Linux tree is a bit out of
date, it doesn't know about CONFIG_ARCH_OMAP_OTG (for the OMAPs that
have OTG silicon).

Teach usbcore how to enumerate OTG devices and perform HNP:

 - CONFIG_USB_OTG is a boolean; it selects CONFIG_USB_SUSPEND.
   Boards with a Mini-AB connector should offer it as a config
   option; no other hardware could support OTG.

 - Before resetting a port, make sure it's not still suspended.
   (For example, after an HNP role switch.)

 - When an OTG A-Host enumerates a dual-role device, set the
   appropriate device feature:  B_HNP_ENABLE if it's connected
   to the OTG port, otherwise A_ALT_HNP_SUPPORT.

 - When an OTG B-Host enumerates a dual-role device, don't
   bother debouncing ... the power session is stable already,
   the A-Host already debounced.

 - The OTG "Targeted Peripheral List" lives in a product-customized
   "otg_whitelist.h" header.

 - CONFIG_USB_OTG_WHITELIST lets developers choose to ignore whitelist
   failures, so unsupported devices can be configured anyway.

 - If the whitelist check fails, immediately suspend the device.

    * For dual-role devices, that triggers HNP so the other device
      can try to act as host.

    * For peripheral-only devices, that conserves power ... but not
      quite as much as turning off power on that port, which should
      eventually be done with OTG ports (and all other ports that
      support SRP).

The whitelist logic tries to make use of the existing usb_device_id
logic, but since the interface info isn't available that early it's
a bit awkward use information anywhere outside the device descriptor.

Generic OTG and reset support for OTG.

 - Declare and use a start_hnp() board-specific procedure.  The OMAP
   implementation will come separately, it can't yet be configured.

 - When OTG is configured, implement the usb_bus_start_enum() hook;
   that just starts a root port reset.

 - When some task (usually khubd) resets a root port, make sure it takes
   the full 50 msec.  The OHCI reset timer is in hardware, and the host
   may need to issue multiple resets to guard against concurrent resume.

 - For backward compatibility, don't kick in the new 50 msec logic unless
   it could be needed:  without CONFIG_USB_SUSPEND, nothing will suspend
   so nothing could resume.  Which is good, at least until we start to
   measure how long a reset takes ... it seems chip-specific.

Define a new usb_bus_start_enum() routine that's available with OTG.
It starts immediate enumeration (port reset) and makes khubd wake up
later.  Non-OTG code could start to use this, given some attention to

Don't clear ep0 status phase handshake during endpoint reset ... at least
one driver emits so much debug output before resetting endpoints that the
reset happens late enough to make the chip break protocol.

Also handle resets IRQs a bit differently:  they can happen twice during

This patch fixes the error in the UHCI driver found by Stuart Hayes.  It
adds the UHCI_PTR_QH bit into the initial entries stored in the hardware
framelist.  It's not entirely clear how the driver ever managed to work
with these bits not set; apparently by coincidence the QH entries
resembled TD entries sufficiently closely to fool the hardware.
