4e19f220d4 USB: RNDIS gadget, fix issues talking from PXA
The reworked Ethernet gadget has an RNDIS interop problem when used
with the CDC subset driver ... e.g. on PXA 2xx and 3xx hardware,
which currently has a hard time talking to MS-Windows hosts.

The issue is that Microsoft requires USB_CLASS_COMM.  Fix by tweaking
the CDC subset driver to not switch to USB_CLASS_VENDOR_SPEC if RNDIS
is used in some other device configuration.

[ UPDATED:  some "statements" were comma-terminated; fix that. ]

* Add smp_lock.h to files which do need it
* Make smp_lock.h include conditional in hardirq.h

5be19a9daa USB: Add Intel Langwell USB Device Controller driver
Intel Langwell USB Device Controller is a High-Speed USB OTG device
controller in Intel Moorestown platform. It can work in OTG device mode
with Intel Langwell USB OTG transceiver driver as well as device-only
mode. The number of programmable endpoints is different through
controller revision.

NOTE:
This patch is the first version Intel Langwell USB OTG device controller
driver. The bug fixing is on going for some hardware and software
issues.  Intel Langwell USB OTG transceiver driver and EHCI driver
patches will be submitted later.

Supported features:
 - USB OTG protocol support with Intel Langwell USB OTG transceiver
   driver (turn on CONFIG_USB_LANGWELL_OTG)
 - Support control, bulk, interrupt and isochronous endpoints
   (isochronous not tested)
 - PCI D0/D3 power management support
 - Link Power Management (LPM) support

Tested gadget drivers:
 - g_file_storage
 - g_ether
 - g_zero

The passed tests:
 - g_file_storage: USBCV Chapter 9 tests
 - g_file_storage: USBCV MSC tests
 - g_file_storage: from/to host files copying
 - g_ether: ping, ftp and scp files from/to host
 - Hotplug, with and without hubs

Known issues:
 - g_ether: failed part of USBCV chap9 tests
 - LPM support not fully tested

TODO:
 - g_ether: pass all USBCV chap9 tests
 - g_zero: pass usbtest tests
 - Stress tests on different gadget drivers
 - On-chip private SRAM caching support

This patch adds support for i.MX3x (only tested with i.MX31 so far) ARM
SoCs to the fsl_usb2_udc driver. It also moves PHY configuration before
controller reset, because otherwise an ULPI PHY doesn't get a reset and
doesn't function after a reboot. The problem with longer control transfers
is still not fixed. The patch renames the fsl_usb2_udc.c file to
fsl_udc_core.c to preserve the same module name for user-space
backwards compatibility.

830d1b188c USB: gadget : Fix RNDIS code to pass USB Compliance tests (USBCV) with g_ether
This patch fixes a bug in the RNDIS code.

Due to this bug gether_connect() fails as the port remains un-initialized.

As a result following USB Compliance Tests were failing.
(1)EndpointDescriptorTest_DeviceConfigured
(2)Interface Descriptor Test.
(3)Halt Endpoint Test.
(4)SetConfigurationTest

The fix aligns rndis code with the CDC ECM for xxx_set_alt().

The above listed USB Compliance test passes with this fix.

Tested working fine on SDP with OMAP 3430.

680cc64557 USB: gadget: imx_udc: don't queue more data when zlp is to be sent
When a zero-length packet has been requested and another packet is
written into the fifo, the MX1 tends to send the first byte of the
previous packet instead of the first byte of the current packet.
The CRC is adjusted accordingly so that this packet is _not_
discarded by the host.

Waiting for the ZLPS bit to clear avoids these bad packets.

2e25134122 USB: gadget: g_serial: append zlp when tx buffer becomes empty
Some usb serial host drivers expect a short packet before they forward
the data to the application. This is caused by them trying to read more
than one packet at a time. So when the gadget sends an exact multiple
of the maximum packet size, it should append a zero-length packet.

367815eea4 USB: pxa27x_udc: single-thread setup requests
Since the PXA 27x UDC automatically ACK's some control
packets such as SET_INTERFACE, the gadgets may not get a
chance to process the request before another control packet
is received. The Linux gadgets do not expect to receive
setup callbacks out of order. The file storage gadget only
saves the "highest" priority request.

The PXA27x UDC driver must make sure it only sends one up at
a time, allowing the gadget to make changes before
continuing. In theory, the host would be NACK'd while the
gadget processes the change but the UDC has already ACK'd
the request. If another request is sent by the host that is
not automatically ACK'd by the UDC, then the throttling
happens properly to regain sync.

The observed case was the file_storage gadget timing out on
a BulkReset request because the SET_INTERFACE was being
processed by the gadget. Since SET_INTERFACE is higher
priority than BulkReset, the BulkReset was dropped.  This
was exacerbated by turning on the debug which delayed the
fsg signal processing thread.

This also fixes the "should never get in
WAIT_ACK_SET_CONF_INTERF state here!!!" warning.

Got pxa27x_udc working on the pxa320 Nomad platform.  The
problem was that the pxa3xx UDC is not quite compatible with
the pxa27x UDC in how it handles back-to-back control
packets.  The pxa27x probably drops them by default, but the
pxa320 does not, and you have to detect it and set the OPC
bit to clear the zero-length packet.

0f43158cad USB: Gadget: fix UTF conversion in the usbstring library
This patch (as1234) fixes a bug in the UTF8 -> UTF-16 conversion
routine in the gadget/usbstring library.  In a UTF-8 multi-byte
sequence, all bytes after the first should have their high-order
two bits set to 10, not 11.

82a10a81c8 USB: g_file_storage: fix use-after-free bug when closing files
This patch (as1231) fixes a use-after-free bug in g_file_storage.  A
device's name may not be available after the device is unregistered,
even if the device structure itself is still allocated.  Since
close_backing_file() prints a LUN's name for debugging, it shouldn't
be called after the LUN has been unregistered.

That whole area needed to be cleaned up; the backing files were
getting closed in a couple of different places.  The patch fixes
things so that they get closed in just one place, as part of the
unbind procedure, immediately before the LUN is unregistered.

237e75bf1e usb gadget: fix ethernet link reports to ethtool
The g_ether USB gadget driver currently decides whether or not there's a
link to report back for eth_get_link based on if the USB link speed is
set. The USB gadget speed is however often set even before the device is
enumerated. It seems more sensible to only report a "link" if we're
actually connected to a host that wants to talk to us. The patch below
does this for me - tested with the PXA27x UDC driver.
