This patch (as1430) fixes a bug in usbcore. When a device
configuration change occurs or a device is removed, the endpoints for
the old config should be completely disabled. However it turns out
they aren't; this is because usb_unbind_interface() calls
usb_enable_interface() or usb_set_interface() to put interfaces back
in altsetting 0, which re-enables the interfaces' endpoints.
As a result, when a device goes through a config change or is
unconfigured, the ep_in[] and ep_out[] arrays may be left holding old
pointers to usb_host_endpoint structures. If the device is
deauthorized these structures get freed, and the stale pointers cause
errors when the the device is eventually unplugged.
The solution is to disable the endpoints after unbinding the
interfaces instead of before. This isn't as large a change as it
sounds, since usb_unbind_interface() disables all the interface's
endpoints anyway before calling the driver's disconnect routine,
unless the driver claims to support "soft" unbind.
This fixes Bugzilla #19192. Thanks to "Tom" Lei Ming for diagnosing
the underlying cause of the problem.

Since commit 461972d8a4c94bc44f11a13046041c78a7cf18dd (musb_core: don't call
musb_platform_exit() twice), unloading the driver module results in a WARNING
"kobject: '(null)' (c73de788): is not initialized, yet kobject_put() is being
called." (or even kernel oops) on e.g. DaVincis, though only in the OTG mode.
There exists dubious and unbalanced put_device() call in musb_free() which
takes place only in the OTG mode. As this commit caused musb_platform_exit()
to be called (and so unregister the NOP transceiver) before this put_device()
call, this function references already freed memory.
On the other hand, all the glue layers miss the otg_put_transceiver() call,
complementary to the otg_get_transceiver() call that they do. So, I think
the solution is to get rid of the strange put_device() call, and instead
call otg_put_transceiver() in the glue layers...

Extends FSL EHCI platform driver glue layer to support
MPC5121 USB controllers. MPC5121 Rev 2.0 silicon EHCI
registers are in big endian format. The appropriate flags
are set using the information in the platform data structure.
MPC83xx system interface registers are not available on
MPC512x, so the access to these registers is isolated in
MPC512x case. Furthermore the USB controller clocks
must be enabled before 512x register accesses which is
done by providing platform specific init callback.
The MPC512x internal USB PHY doesn't provide supply voltage.
For boards using different power switches allow specifying
DRVVBUS and PWR_FAULT signal polarity of the MPC5121 internal
PHY using "fsl,invert-drvvbus" and "fsl,invert-pwr-fault"
properties in the device tree USB nodes. Adds documentation
for this new device tree bindings.

Replace FSL USB platform code by simple platform driver for
creation of FSL USB platform devices.
The driver creates platform devices based on the information
from USB nodes in the flat device tree. This is the replacement
for old arch fsl_soc usb code removed by this patch. The driver
uses usual of-style binding, available EHCI-HCD and UDC
drivers can be bound to the created devices. The new of-style
driver additionaly instantiates USB OTG platform device, as the
appropriate USB OTG driver will be added soon.

commit 633ba7876b96ec339ef685357e2f7c60b5a8ce85 broke
g_file_storage functionality by enabling AUTOCLEAR on
all cases without caring for all gadget drivers.
This patch will only enable AUTOCLEAR if our endpoint's
FIFO was configured with double buffering support. Note
this is not a complete fix, double buffered case still
doesn't work always, but that hasn't been working for
quite some time. Other than reverting the entire commit
and breaking testusb with double buffered case again,
I decided it was better to fix the single buffered case
and spend more time fixing double buffered case properly.

Enabling CONFIG_USB_MUSB_DEBUG option causes -DDEBUG to be added to gcc's
command line, however the DBG() macro doesn't depend on DEBUG, so that the
debugging messages get printed regardless of the option, and I don't think
that this was intended. Get rid of otherwise unused xprintk() macro and make
DBG() macro directly call pr_debug() which only results in the actual code
generated if DEBUG is defined.
This change makes musb_hdrc.o ~30% less in size with CONFIG_USB_MUSB_DEBUG
disabled (in host mode).

this patch to qcserial.c enables the Diagnostics Monitor
and NMEA GPS ports on Qualcomm Gobi 2000 devices.
A Gobi 2000 device will provide 3 serial ports:
# /dev/ttyUSB0 -> Diagnostics
# /dev/ttyUSB1 -> 3G Modem
# /dev/ttyUSB2 -> NMEA GPS port
* The Diagnostics Monitor uses Qualcomm's DM protocol; I used
libqcdm (ModemManager) to talk to it, found it working, but at
least DM commands 12 and 64 are not implemented on my device
(Gobi 2000 built into Thinkpad x100e).
* Functionality of the 3G Modem port remains unchanged.
* The GPS port and how to enable it has been confirmed now in the
Gobi 3000 source code at:
https://www.codeaurora.org/patches/quic/gobi/
Enable/disable GPS via:
echo "\$GPS_START" > /dev/ttyUSB2
# use GPS
echo "\$GPS_STOP" > /dev/ttyUSB2

This reverts commit 6a1a82df91fa0eb1cc76069a9efe5714d087eccd.
RTS and DTR should not be modified based on CRTSCTS when calling
set_termios.
Modem control lines are raised at port open by the tty layer and should stay
raised regardless of whether hardware flow control is enabled or not.
This is in conformance with the way serial ports work today and many
applications depend on this behaviour to be able to talk to hardware
implementing hardware flow control (without the applications actually using
it).
Hardware which expects different behaviour on these lines can always
use TIOCMSET/TIOCMBI[SC] after port open to change them.

This patch, adds to the option driver the Onda Communication
(http://www.ondacommunication.com) vendor id, and the MT825UP modem
device id.
Note that many variants of this same device are being release here in
Italy (at least one or two per telephony operator).
These devices are perfectly equivalent except for some predefined
settings (which can be changed of course).
It should be noted that most ONDA devices are allready supported (they
used other vendor's ids in the past). The patch seems working fine here,
and the rest of the driver seems uninfluenced.
