A static usb-serial-driver structure that is used to initialise the
interrupt URB was modified during probe depending on the currently
probed device type, something which could break a parallel probe of a
device of a different type.
Fix this up by overriding the default completion callback for MCS7715
devices in attach() instead. We may want to use two usb-serial driver
instances for the two types later.

Changing the LCR register after initialization does not seem to be reliable
on all chips (particularly not on CH341A). Restructure initialization and
configuration to always reinit the chip on configuration changes instead and
pass the LCR register value directly to the initialization command.
(Note that baud rates above 500kbaud are incorrect, but they're incorrect in
the same way both before and after this patch at least on the CH340G. Fixing
this isn't a priority as higher baud rates don't seem that reliable anyway.)

This patch adds support for the GPIO found on the CP2105. Unlike the GPIO
provided by some of the other devices supported by the cp210x driver, the
GPIO on the CP2015 is muxed on pins otherwise used for serial control
lines. The GPIO have been configured in 2 separate banks as the choice to
configure the pins for GPIO is made separately for pins shared with each
of the 2 serial ports this device provides, though the choice is made for
all pins associated with that port in one go. The choice of whether to use
the pins for GPIO or serial is made by adding configuration to a one-time
programable PROM in the chip and can not be changed at runtime. The device
defaults to GPIO.
This device supports either push-pull or open-drain modes, it doesn't
provide an explicit input mode, though the state of the GPIO can be read
when used in open-drain mode. Like with pin use, the mode is configured in
the one-time programable PROM and can't be changed at runtime.

parport subsystem has introduced parport_del_port() to delete a port
when it is going away. Without parport_del_port() the registered port
will not be unregistered.
To reproduce and verify the error:
Command to be used is : ls /sys/bus/parport/devices
1) without the device attached there is no output as there is no
registered parport.
2) Attach the device, and the command will show "parport0".
3) Remove the device and the command still shows "parport0".
4) Attach the device again and we get "parport1".
With the patch applied:
1) without the device attached there is no output as there is no
registered parport.
2) Attach the device, and the command will show "parport0".
3) Remove the device and there is no output as "parport0" is now
removed.
4) Attach device again to get "parport0" again.

The interface read URB is submitted in attach, but was only unlinked by
the driver at disconnect.
In case of a late probe error (e.g. due to failed minor allocation),
disconnect is never called and we would end up with active URBs for an
unbound interface. This in turn could lead to deallocated memory being
dereferenced in the completion callback.

This reverts commit 0b2b093ad4.
Turns out the MOXA vendor driver was basically just a copy of the
ti_usb_3410_5052 driver. We don't want two drivers for the same chip
even if mxu11x0 had gotten some much needed clean up before merge. So
let's remove the mxu11x0 driver, add support for these Moxa devices to
the TI driver, and then clean that driver up instead.

The DEVICE_HWI type was added under the faulty assumption that Huawei
devices based on Qualcomm chipsets and firmware use the static USB
interface numbering known from Gobi devices. But this model does
not apply to Huawei devices like the HP branded lt4112 (Huawei me906e).
Huawei firmwares will dynamically assign interface numbers. Functions
are renumbered when the firmware is reconfigured.
Fix by changing the DEVICE_HWI type to use a simplified version
of Huawei's subclass + protocol scheme: Blacklisting known network
interface combinations and assuming the rest are serial.

Add helper to access line-control register in order to work around a
cp2108 GET_LINE_CTL bug.
cp2108 GET_LINE_CTL returns the 16-bit value with the 2 bytes swapped.
However, SET_LINE_CTL functions properly. When the driver tries to modify
the register, it reads it, modifies some bits and writes back. Because the
read bytes were swapped, this often results in an invalid value to be
written. In turn, this causes cp2108 respond with a stall. The stall
sometimes doesn't clear properly and cp2108 starts responding to following
valid commands also with stalls, effectively failing.

This change is preparation for implementing a cp2108 bug workaround.
The workaround requires storing some private data. Right now the data is
attached to the USB interface and allocated in the attach() callback.
The bug detection requires USB I/O which is done easier from port_probe()
callback rather than attach(). Since the USB access functions take port
as a parameter, and since the private data is used exclusively by these
functions, it can be allocated in port_probe(). Also, all cp210x devices
have exactly 1 port per USB iterface, so moving private data from the USB
interface to port is trivial.

Flush all device queues at close in order to work around a cp2108 Tx
queue bug.
Occasionally, writing data and immediately closing the port makes cp2108
stop responding. The device has to be unplugged to clear the error.
The failure is induced by shutting down the device while its Tx queue
still has unsent data. This condition is avoided by issuing PURGE command
from the close() callback.
This change is applied to all cp210x devices. Clearing internal queues on
close is generally good.

Only the option driver implements the send_setup callback; it uses the

This is a partial, context modified revert of commit e463c6dda8
("USB: option: handle send_setup blacklisting at probe"), which
introduced an unnecessary struct option_private for storing the
interface number used in option_send_setup. Removing this struct
will allow option_send_setup to be generalized for other drivers.

Fix potential null-pointer dereference at probe by making sure that the

The whiteheat driver assumes there are at least five pairs of bulk

attempt to bind to an interface with fewer bulk endpoints would
currently lead to an oops.

USB-serial updates for v4.3-rc1
Here's a fix for a long-standing issue with the pl2303 divisor
calculations that affects some non-standard baudrates that were enabled

When using Edgeport/416 models with newer firmware (sometime after
firmware version 4.80.0), idle ports are automatically bounced
(disconnected and then reconnected) approximately every 60 seconds.
This breaks programs (e.g: minicom) where idle periods are common,
normal and expected.
I confirmed with the manufacturer (Digi International) that Edgeport/416
models now ship from the factory with firmware that expects periodic
"heartbeat" queries from the driver to keep idle ports alive. This
patch implements heartbeat support using the mechanism Digi suggested
(periodically requesting an I2C descriptor address) that appears effective
on Edgeports running the newer firmware (that require it) and benign on
Edgeport devices running older firmware. Since we know that Edgeport
firmware version 4.80 (the version distributed in /lib/firmware/down3.bin
and used for Edgeports that are either running still older versions or
have no onboard non-volatile firmware image) does not require heartbeat
support, this patch schedules heartbeats only on Edgeport/416 devices,
and only if they are running firmware versions newer than 4.80.

Do what we can to verify that the driver's firmware image is valid
(before attempting to download it to the Edgeport) by adding a new
function, check_fw_sanity(), and a call to it in in download_fw().
Note: It looks like some Edgeports (models like the EP/416 with on-board
E2PROM) may be able to function even if the on-disk firmware image is
bad or missing, iff their local E2PROM versions are valid. But most
Edgeport models (I've tried EP/1 and EP/8) do not appear to have this
capability and they always rely on the on-disk firmware image.
I tested an implementation that calls the new check_fw_sanity()
function at the top of download_fw() and, rather than simply returning
an error if the firmware image is bad or missing, it saves the result
and defers the decision until later when it may find that it is running
on a E2PROM-equipped device with a valid image. But I think this is
messier than it is worth (adding still more messiness to the already
very messy download_fw()) for such a marginal possible benefit. So, at
least for now, I have chosen the much simpler approach of returning an
error whenever edge_startup() fails to load an on-disk firmware image, or
check_fw_sanity() indicates that it is unusable.

The io_ti driver fails to download firmware to Edgeport
devices such as the EP/416, even when the on-disk firmware image
(/lib/firmware/edgeport/down3.bin) is more current than the version
on the EP/416. The current download code is broken in a few ways.
Notably it mis-uses global variables OperationalMajorVersion and
OperationalMinorVersion (reading their values before they've been
properly initialized and subsequently initializing them multiple times
without synchronization). This patch drops the global variables and
replaces the redundant calls to request_firmware()/release_firmware()
in download_fw() with a single call pair in edge_startup(); the firmware
image pointer is then passed to download_fw() and build_i2c_fw_hdr().

This commit fixes the following issues:
1. The 9th bit of buf was believed to be the LSB of divisor's
exponent, but the hardware interprets it as MSB (9th bit) of the
mantissa. The exponent is actually one bit shorter and applies
to base 4, not 2 as previously believed.
2. Loop iterations doubled the exponent instead of incrementing.
3. The exponent wasn't checked for overflow.
4. The function returned requested rate instead of actual rate.
Due to issue #2, the old code deviated from the wrong formula
described in #1 and actually yielded correct rates when divisor
was lower than 4096 by using exponents of 0, 2 or 4 base-2,
interpreted as 0, 1, 2 base-4 with the 9th mantissa bit clear.
However, at 93.75 kbaud or less the rate turned out too slow
due to #2 or too fast due to #2 and #3.
I tested this patch by sending and validating 0x00,0x01,..,0xff
to an FTDI dongle at 234, 987, 2401, 9601, 31415, 115199, 250k,
500k, 750k, 1M, 1.5M, 3M+1 baud. All rates passed.
I also used pv to check speed at some rates unsupported by FTDI:
45 (the lowest possible), 2M, 4M, 5M and 6M-1. Looked sane.

Add support for the Sierra Wireless AR8550 device with
USB descriptor 0x1199, 0x68AB.
It is common with MC879x modules 1199:683c/683d which
also are composite devices with 7 interfaces (0..6)
and also MDM62xx based as the AR8550.
The major difference are only the interface attributes
02/02/01 on interfaces 3 and 4 on the AR8550. They are
vendor specific ff/ff/ff on MC879x modules.

SSD.
To work around this conflict, I've dug up a mailing list post [1] from a
long time ago, in which a user posts the full USB descriptor
information. The most specific value in this appears to be the interface
class, which has value 255 (0xff). Since usb-storage requires an
interface class of 0x8, I believe it's correct to disambiguate the two
devices by matching on 0xff inside visor.

Fix up the f81232 driver, which up to this point has mostly been a
placeholder without a proper implementation.
Included is also a minor clean up of ch341.
