USB: serial: f81232: implement break control

2019-05-03T07:19:55+00:00

Implement Fintek F81232 break on/off with LCR register. It's the same with 16550A LCR register layout. Signed-off-by: Ji-Ze Hong (Peter Hong) [ johan: fix corrupt line settings on break due to missing shadow_lcr update in set_termios() ] Signed-off-by: Johan Hovold

USB: serial: f81232: add high baud rate support

2019-05-03T07:19:54+00:00

The F81232 had 4 clocksource 1.846/18.46/14.77/24MHz and baud rates can be up to 1.5Mbits with 24MHz. F81232 Clock registers (106h) Bit1-0: Clock source selector 00: 1.846MHz. 01: 18.46MHz. 10: 24MHz. 11: 14.77MHz. Signed-off-by: Ji-Ze Hong (Peter Hong) Signed-off-by: Johan Hovold

USB: serial: f81232: clear overrun flag

2019-05-03T07:19:54+00:00

The F81232 will report data and LSR with bulk like following format: bulk-in data: [LSR(1Byte)+DATA(1Byte)][LSR(1Byte)+DATA(1Byte)]... LSR will auto clear frame/parity/break error flag when reading by H/W, but overrrun will only cleared when reading LSR. So this patch add a worker to read LSR when overrun and flush the worker on close() & suspend(). Cc: Oliver Neukum Signed-off-by: Ji-Ze Hong (Peter Hong) Signed-off-by: Johan Hovold

USB: serial: f81232: fix interrupt worker not stop

2019-05-03T07:18:31+00:00

The F81232 will use interrupt worker to handle MSR change. This patch will fix the issue that interrupt work should stop in close() and suspend(). This also fixes line-status events being disabled after a suspend cycle until the port is re-opened.

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.
