This patch (as1263) fixes a mixup that occurred when conflicting
patches for the sierra driver were merged incorrectly.  The former
sierra_shutdown routine should have been become sierra_release, not
sierra_disconnect.

The symptom this fixes is an oops when the device file is closed after
a Sierra device has been unplugged (Bugzilla #13675).

Add A-Link 3GU device id 1e0e:9200 into option driver. The device
has 4 interfaces, of which 1 is handled by storage and the other 3
by option driver.

The device appears first as CD-only 1e0e:f000 device and must be
switched to 1e0e:9200 mode either by using "eject CD" or
usb_modeswitch.

For the record, the device does not work with generic usbserial
driver (usb disconnect when sending the ATDT command).

It enhances the driver for FTDI-based USB serial adapters to recognize and
support Northern Digital Inc (NDI) measurement equipment. NDI has been
providing this patch for various kernel flavors for several years and we would
like to see these changes built in to the driver so that our equipement works
without the need for customers to patch the kernel themselves.

The patch makes small modifications to 2 files: ./drivers/usb/serial/ftdi_sio.c
and ./drivers/usb/serial/ftdi_sio.h. It accomplishes 3 things:

1. Define the VID and PIDs to allow the driver to recognize the NDI devices.
2. Map the 19200 baud rate setting to our higher baud rate of 1.2Mb
   We would have chosen to map 38400 to the higher rate, similar to what
   several other vendors have done, but some of our legacy customers actually
   use 38400, therefore we remap 19200 to the higher rate.
3. We set the default transmit latency in the FTDI chip to 1ms for our devices.
   Our devices are typically polled at 60Hz and the default ftdi latency
   seriously affects turn-around time and results in missed data frames. We
   have created a modprobe option that allows this setting to be increased.
   This has proven necessary particularly in some virtualized environments.

This reverts commit cc71329b, so that
Red Hat machines can boot properly.  It seems that the Red Hat initrd
code tries to watch the /proc/bus/usb/devices file to monitor usb

not show the true state of the system, they seem to like it.

So for now, don't move this option under the EMBEDDED config option.

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.

The commit 335f8514 introduced a
regression which stopped usb consoles from working correctly as a
kernel boot console as well as interactive login device.

The addition of the serial_close() which in turn calls
tty_port_close_start() will change the reference count of port.count
and warn about it.  The usb console code had previously incremented
the port.count to indicate it was making use of the device as a
console and the forced change causes a double open on the usb device
which leads to a non obvious kernel oops later on when the tty is
freed.

To fix the problem instead make use of port->console to track if the
port is in fact an active console port to avoid double initialization
of the usb serial device.  The port.count is incremented and
decremented only with in the scope of usb_console_setup() for the
purpose of the low level driver initialization.

This patch (as1257) revises the way ehci-hcd detects STALLs.  The
logic is a little peculiar because there's no hardware status bit
specifically meant to indicate a STALL.  You just have to guess that a
STALL was received if the BABBLE bit (which is fatal) isn't set and
the transfer stopped before all its retries were used up.

The existing code doesn't do this properly, because it tests for MMF
(Missed MicroFrame) and DBE (Data Buffer Error) before testing the
retry counter.  Thus, if a transaction gets either MMF or DBE the
corresponding flag is set and the transaction is retried.  If the
second attempt receives a STALL then -EPIPE is the correct return
value.  But the existing code would see the MMF or DBE flag instead
and return -EPROTO, -ENOSR, or -ECOMM.

This patch (as1256) changes ehci-hcd and all the other drivers in the
EHCI family to make use of the new clear_tt_buffer callbacks.  When a
Clear-TT-Buffer request is in progress for a QH, the QH is not allowed
to be linked into the async schedule until the request is finished.
At that time, if there are any URBs queued for the QH, it is linked
into the async schedule.

This patch (as1255) updates the interface for calling
usb_hub_clear_tt_buffer().  Even the name of the function is changed!

When an async URB (i.e., Control or Bulk) going through a high-speed
hub to a non-high-speed device is cancelled or fails, the hub's
Transaction Translator buffer may be left busy still trying to
complete the transaction.  The buffer has to be cleared; that's what
usb_hub_clear_tt_buffer() does.

It isn't safe to send any more URBs to the same endpoint until the TT
buffer is fully clear.  Therefore the HCD needs to be told when the
Clear-TT-Buffer request has finished.  This patch adds a callback
method to struct hc_driver for that purpose, and makes the hub driver
invoke the callback at the proper time.

The patch also changes a couple of names; "hub_tt_kevent" and
"tt.kevent" now look rather antiquated.

Get rid of some obnoxious and inappropriate messaging, mostly on
DaVinci, when usbcore tries to autosuspend a root hub if just a
mini/micro-A connector is connected.  Symptom: endless stream of
messages reading like:

 musb_bus_suspend 2221: trying to suspend as a_wait_vrise is_active=1

Improve that musb bus suspend primitive a bit.  Take advantage of
this call to update the OTG state machine if appropriate, moving
the device out of the A_WAIT_VRISE state.  There's basically no
timer for that state transition just now, except with tusb6010;
that can make trouble.

This is an update to the "usb-ehci-update-toggle-state-for-linked-qhs"
patch.  Since an HCD's endpoint_reset method can be called in
interrupt context, it mustn't assume that interrupts are enabled or
that it can sleep.

So we revert to the original way of refreshing QHs' toggle bits.  Now
the endpoint_reset method merely clears the toggle flag in the device
structure (as was done before) and starts an async QH unlink.  When the
QH is linked again, after the unlink finishes and an URB is queued,
the qh_refresh() routine will update the QH's toggle bit.
