USB: serial: drop unused iflag macro

2019-04-30T08:26:32Z

Drop the RELEVANT_IFLAG() macro which essentially hasn't been used for over a decade except in some remnant debug printks that were recently removed. Reviewed-by: Greg Kroah-Hartman Signed-off-by: Johan Hovold

USB: serial: clean up throttle handling

2019-04-30T08:23:29Z

Clean up the throttle implementation by dropping the redundant throttle_req flag which was a remnant from back when there was only a single read URB. Also convert the throttled flag to an atomic bit flag. Signed-off-by: Johan Hovold

usb-serial: begin switching to ->[sg]et_serial()

2018-10-13T04:50:34Z

add such methods for usb_serial_driver, provide tty_operations ->[sg]et_serial() calling those. For now the lack of methods in driver means ENOIOCTLCMD from usb-serial ->[sg]et_serial(), making tty_ioctl() fall back to calling ->ioctl(). Once all drivers are converted, we'll be returning -ENOTTY instead, completing the switchover. Reviewed-by: Johan Hovold Signed-off-by: Al Viro

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

2017-11-04T10:48:02Z

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: add calc_num_ports callback to generic driver

2017-03-28T08:54:39Z

Add a calc_num_ports callback to the generic driver and verify that the device has the required endpoints there instead of in core. Note that the generic driver num_ports field was never used. Signed-off-by: Johan Hovold

USB: serial: allow subdrivers to modify port-endpoint mapping

2017-03-28T08:54:39Z

Allow subdrivers to modify the port-endpoint mapping by passing the endpoint descriptors to calc_num_ports. The callback can now also be used to verify that the required endpoints exists and abort probing otherwise. This will allow us to get rid of a few hacks in subdrivers that are already modifying the port-endpoint mapping (or aborting probe due to missing endpoints), but only after the port structures have been setup.

USB: serial: add endpoint sanity check to core

2017-03-16T09:33:41Z

Allow drivers to specify a minimum number of endpoints per type, which USB serial core will verify after subdriver probe has returned (where the current alternate setting may have been changed). Signed-off-by: Johan Hovold

USB: serial: allow up to 16 ports per device

2017-03-16T09:33:40Z

Raise the arbitrary limit of how many ports a single device can claim from eight to 16. This specifically enables the upper eight ports of some mxuport devices. Signed-off-by: Johan Hovold

USB: serial: clean up endpoint and port-counter types

2017-03-16T09:13:37Z

Use unsigned-char type for the endpoint and port counters. Signed-off-by: Johan Hovold

Revert "USB: serial: make bulk_out_size a lower limit"

2015-02-26T16:02:15Z

This reverts commit 5083fd7bdfe6760577235a724cf6dccae13652c2. A bulk-out size smaller than the end-point size is indeed valid. The offending commit broke the usb-debug driver for EHCI debug devices, which use 8-byte buffers.
