USB: serial: do not use tty class device for debugging

2021-04-09T15:55:21+00:00

Use the port struct device rather than tty class device for debugging.

Note that while USB serial doesn't support serdev yet (due to serdev not
handling hotplugging), serdev ttys do not have a corresponding class
device and would have been logged using a "(NULL device *):" prefix.

USB: serial: make remove callback return void

2021-02-09T12:13:58+00:00

All usb_serial drivers return 0 in their remove callbacks and driver
core ignores the value returned by usb_serial_device_remove(). So change
the remove callback to return void and return 0 unconditionally in
usb_serial_device_remove().

USB: serial: upd78f0730: drop short control-transfer check

2021-01-18T13:26:32+00:00

There's no need to check for short control transfers when sending data
so remove the redundant sanity check.

USB: serial: use fallthrough pseudo-keyword

2020-07-08T12:55:35+00:00

Replace the existing /* fall through */ comments and its variants with
the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary
fall-through markings when it is the case.

USB: serial: Remove redundant license text

2017-11-04T10:55:38+00:00

Now that the SPDX tag is in all USB files, that identifies the license
in a specific and legally-defined manner.  So the extra GPL text wording
can be removed as it is no longer needed at all.

This is done on a quest to remove the 700+ different ways that files in
the kernel describe the GPL license text.  And there's unneeded stuff
like the address (sometimes incorrect) for the FSF which is never
needed.

No copyright headers or other non-license-description text was removed.

USB: add SPDX identifiers to all remaining files in drivers/usb/

2017-11-04T10:48:02+00:00

It's good to have SPDX identifiers in all files to make it easier to
audit the kernel tree for correct licenses.

Update the drivers/usb/ and include/linux/usb* files with the correct
SPDX license identifier based on the license text in the file itself.
The SPDX identifier is a legally binding shorthand, which can be used
instead of the full boiler plate text.

This work is based on a script and data from Thomas Gleixner, Philippe
Ombredanne, and Kate Stewart.

USB: serial: upd78f0730: make constants static

2017-06-01T09:07:50+00:00

Some local constants don't change from call to call and are good
candidates to become static. This will prevent copying of these
constants to stack during runtime.

The adaptor on Analog Devices EVAL-ADXL362Z development board is used
to flash and debug firmware of on-board Renesas RL78/G13 MCU.
Also added support of the 153600 baud rate, since the stock firmware
uses it.

USB: serial: add uPD78F0730 USB to Serial Adaptor Driver

2017-01-26T09:18:17+00:00

The adaptor can be found on development boards for 78k, RL78 and V850
microcontrollers produced by Renesas Electronics Corporation.

This is not a full-featured USB to serial converter, however it allows
basic communication and simple control which is enough for programming of
on-board flash and debugging through a debug monitor.

uPD78F0730 is a USB-enabled microcontroller with USB-to-UART conversion
implemented in firmware.

This chip is also present in some debugging adaptors which use it for
USB-to-SPI conversion as well. The present driver doesn't cover SPI,
only USB-to-UART conversion is supported.
