      USB: serial: option: add HP lt4132 · cc0667b5
      由 Tore Anderson 提交于 
      commit d57ec3c83b5153217a70b561d4fb6ed96f2f7a25 upstream.

The HP lt4132 is a rebranded Huawei ME906s-158 LTE modem.

The interface with protocol 0x16 is "CDC ECM & NCM" according to the *.inf
files included with the Windows driver. Attaching the option driver to it
doesn't result in a /dev/ttyUSB* device being created, so I've excluded it.
Note that it is also excluded for corresponding Huawei-branded devices, cf.
commit d544db29 ("USB: support new huawei devices in option.c").

      USB: serial: console: fix reported terminal settings · 9d9026af
      由 Johan Hovold 提交于 
      commit f51ccf46217c28758b1f3b5bc0ccfc00eca658b2 upstream.

The USB-serial console implementation has never reported the actual
terminal settings used. Despite storing the corresponding cflags in its
struct console, these were never honoured on later tty open() where the
tty termios would be left initialised to the driver defaults.

Unlike the serial console implementation, the USB-serial code calls
subdriver open() already at console setup. While calling set_termios()
and write() before open() looks like it could work for some USB-serial
drivers, others definitely do not expect this, so modelling this after
serial core is going to be intrusive, if at all possible.

Instead, use a (renamed) tty helper to save the termios data used at
console setup so that the tty termios reflects the actual terminal
settings after a subsequent tty open().

Note that the calls to tty_init_termios() (tty_driver_install()) and
tty_save_termios() are serialised using the disconnect mutex.

This specifically fixes a regression that was triggered by a recent
change adding software flow control to the pl2303 driver: a getty trying
to disable flow control while leaving the baud rate unchanged would now
also set the baud rate to the driver default (prior to the flow-control
change this had been a noop).

Fixes: 7041d9c3 ("USB: serial: pl2303: add support for tx xon/xoff flow control")

      USB: serial: option: add two-endpoints device-id flag · 35aecc02
      由 Johan Hovold 提交于 
      Allow matching on interfaces having two endpoints by adding a new
device-id flag.

This allows for the handling of devices whose interface numbers can
change (e.g. Quectel EP06) to be contained in the device-id table.

      USB: serial: option: improve Quectel EP06 detection · 36cae568
      由 Kristian Evensen 提交于 
      The Quectel EP06 (and EM06/EG06) LTE modem supports updating the USB
configuration, without the VID/PID or configuration number changing.
When the configuration is updated and interfaces are added/removed, the
interface numbers are updated. This causes our current code for matching
EP06 not to work as intended, as the assumption about reserved
interfaces no longer holds. If for example the diagnostic (first)
interface is removed, option will (try to) bind to the QMI interface.

This patch improves EP06 detection by replacing the current match with
two matches, and those matches check class, subclass and protocol as
well as VID and PID. The diag interface exports class, subclass and
protocol as 0xff. For the other serial interfaces, class is 0xff and
subclass and protocol are both 0x0.

The modem can export the following devices and always in this order:
diag, nmea, at, ppp. qmi and adb. This means that diag can only ever be
interface 0, and interface numbers 1-5 should be marked as reserved. The
three other serial devices can have interface numbers 0-3, but I have
not marked any interfaces as reserved. The reason is that the serial
devices are the only interfaces exported by the device where subclass
and protocol is 0x0.

QMI exports the same class, subclass and protocol values as the diag
interface. However, the two interfaces have different number of
endpoints, QMI has three and diag two. I have added a check for number
of interfaces if VID/PID matches the EP06, and we ignore the device if
number of interfaces equals three (and subclass is set).

      USB: option: add support for DW5821e · 7bab01ec
      由 Aleksander Morgado 提交于 
      The device exposes AT, NMEA and DIAG ports in both USB configurations.

The patch explicitly ignores interfaces 0 and 1, as they're bound to
other drivers already; and also interface 6, which is a GNSS interface
for which we don't have a driver yet.

      USB: serial: cp210x: implement GPIO support for CP2102N · c8acfe0a
      由 Karoly Pados 提交于 
      This patch adds GPIO support for CP2102N devices.

It introduces new generic code to support emulating separate
input and outputs directions even though these devices
only know output modes (open-drain and pushpull). Existing
GPIO support for CP2105 has been migrated over to the new
code structure.

Only limitation is that for the QFN28 variant, only 4 out of
7 GPIOs are supported. This is because the config array
locations of the last 3 pins are not documented, and reverse
engineering revealed offsets that conflicted with other
documented functions. Hence we'll play it safe instead
until somebody clears this up further.
