Dell DW5829e same as DW5821e except CAT level.
DW5821e supports CAT16 but DW5829e supports CAT9.
There are 2 types product of DW5829e: normal and eSIM.
So we will add 2 PID for DW5829e.
And for each PID, it support MBIM or RMNET.
Let's see test evidence as below:
DW5829e MBIM mode:

BTW, the interface 0x6 of MBIM mode is GNSS port, which not same as NMEA
port. So it's banned from serial option driver.
The remaining interfaces 0x2-0x5 are: MODEM, MODEM, NMEA, DIAG.

This reverts commit 46ee4abb10a07bd8f8ce910ee6b4ae6a947d7f63.
CH341 has Product ID 0x5512 in EPP/MEM mode which is used for
I2C/SPI/GPIO interfaces. In asynchronous serial interface mode
CH341 has PID 0x5523 which is already in the table.
Mode is selected by corresponding jumper setting.

Programmable lab power supplies made by GW Instek, such as the
GPP-2323, have a USB port exposing a serial port to control the device.
Stringing the supplied Windows driver, references to the ch341 chip are
found. Binding the existing ch341 driver to the VID/PID of the GPP-2323
("GW Instek USB2.0-Serial" as per the USB product name) works out of the
box, communication and control is now possible.
This patch should work with any GPP series power supply due to
similarities in the product line.

When generalising GPIO support and adding support for CP2102N, the GPIO
registration for some CP2105 devices accidentally broke. Specifically,
when all the pins of a port are in "modem" mode, and thus unavailable
for GPIO use, the GPIO chip would now be registered without having
initialised the number of GPIO lines. This would in turn be rejected by
gpiolib and some errors messages would be printed (but importantly probe
would still succeed).
Fix this by initialising the number of GPIO lines before registering the
GPIO chip.
Note that as for the other device types, and as when all CP2105 pins are
muxed for LED function, the GPIO chip is registered also when no pins
are available for GPIO use.

- VID:PID 2cb7:01a2, FM101-GL are laptop M.2 cards (with
MBIM interfaces for /Linux/Chrome OS)
- VID:PID 2cb7:01a4, FM101-GL for laptop debug M.2 cards(with adb
interface for /Linux/Chrome OS)

datasheet claims. Add it to the list of known release numbers for the

Note the chip type could only be determined indirectly based on its

Here are the USB-serial updates for 5.16-rc1, including:
- conversions of usb_control_msg() calls to use the new wrappers where
appropriate
- fix of the keyspan probe error handling after a low-order allocation
failure (e.g. due to fault injection)
- allow hung up ports to be runtime suspended
Included are also some related clean ups.

The new wrapper functions for usb_control_msg() can accept data from

Some CP2102 do not support event-insertion mode but return no error when
attempting to enable it.
This means that any event escape characters in the input stream will not
be escaped by the device and consequently regular data may be
interpreted as escape sequences and be removed from the stream by the
driver.
The reporter's device has batch number DCL00X etched into it and as
discovered by the SHA2017 Badge team, counterfeit devices with that
marking can be detected by sending malformed vendor requests. [1][2]
Tests confirm that the possibly counterfeit CP2102 returns a single byte
in response to a malformed two-byte part-number request, while an
original CP2102 returns two bytes. Assume that every CP2102 that behaves
this way also does not support event-insertion mode (e.g. cannot report
parity errors).

appropriate and remove DMA buffers from the callers.

The new wrapper functions usb_control_msg_send/recv accept stack
variables for USB message buffers and eliminate the need of manually
allocating temporary DMA buffers. The read wrapper also treats short
reads as errors. Hence use the wrappers instead of using
usb_control_msg() directly.
Note that the conversion of f81534a_ctrl_set_register() adds an extra an
extra allocation and memcpy for every retry. Since this function is
called rarely and retries are hopefully rare, the overhead should be
acceptable.
Also note that short reads are now logged as -EREMOTEIO instead of
indicating the amount of data read.

User space can keep a tty open indefinitely and that should not prevent
a hung up port and its USB device from being runtime suspended.
Fix this by incrementing the PM usage counter when the port it activated
and decrementing the counter when the port is shutdown rather than when
the tty is installed and the last reference is dropped, respectively.

"Here is the big set of driver core patches for 5.15-rc1.
These do change a number of different things across different

might have already come into your tree from different pulls that did
the following
- changed the bus remove callback to return void
- sysfs iomem_get_mapping rework
Other than those two things, there's only a few small things in here:
- kernfs performance improvements for huge numbers of sysfs users at
once
- tiny api cleanups

This reverts commit 3c18e9baee0ef97510dcda78c82285f52626764b.
These devices do not appear to send a zero-length packet when the
transfer size is a multiple of the bulk-endpoint max-packet size. This
means that incoming data may not be processed by the driver until a
short packet is received or the receive buffer is full.
Revert back to using endpoint-sized receive buffers to avoid stalled
reads.
