2020-07-07USB: serial: ch341: fix missing simulated-break marginMichael Hanselmann
On devices which do not support break signalling a break condition is simulated by sending a NUL byte at the lowest possible speed. The break condition will be 9 bit periods long (start bit and eight data bits), but the transmission itself also includes the stop bit. Add the missing safety margin of one bit which is intended to account for timing differences, and fix up the corresponding comment.

2020-07-06USB: serial: ch341: simulate break condition if not supportedMichael Hanselmann
A subset of all CH341 devices don't support a real break condition. This fact is already used in the "ch341_detect_quirks" function. With this change a quirk is implemented to simulate a break condition by temporarily lowering the baud rate and sending a NUL byte. The primary drawbacks of this approach are that the duration of the break can't be controlled by userland and that data incoming during a simulated break is corrupted. The "TTY_DRIVER_HARDWARE_BREAK" serial driver flag was investigated as an alternative. It's a driver-wide flag and would've required significant changes to the serial and USB-serial driver frameworks to expose it for individual USB-serial adapters. Tested by sending a break condition and watching the TX pin using an oscilloscope.

No idea why this driver is using a char device node, statically allocated, with no dynamic allocation or hook up with devtmpfs, along with a reserverd major number, for "special" operations, not all of which ever were implemented. So just rip it out, as no one must be using it because no modern system will ever actually create the /dev/ node it needs.

This file has a HUGE debugging sysfs file that spews out a lot of information all at once, which violates the one-value-per-file rule for sysfs. If this is really needed, it should go into debugfs, but given the age of this driver, I strongly doubt anyone is using it anymore. So just remove the file entirely, it was never documented, so obviously, no one actually needed it :) Cc: Felipe Balbi <balbi@kernel.org> Reviewed-by: Ran Wang <ran.wang_1@nxp.com> Link: https://lore.kernel.org/r/20200702072914.1072878-1-gregkh@linuxfoundation.org Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2020-07-03usb: host: pci-quirks: Demote function header from kerneldoc to comment blockLee Jones
quirk_usb_handoff_xhci()'s function header is the only one across the sourcefile which is denoted as a kerneldoc header. Despite no attempt to document its arguments. Drop it down in status from kerneldoc to a standard comment block to match the other headers in the file. Fixes the following W=1 kernel build warning: drivers/usb/host/pci-quirks.c:1145: warning: Function parameter or member 'pdev' not described in 'quirk_usb_handoff_xhci' Cc: Mathias Nyman <mathias.nyman@intel.com> Cc: Martin Mares <mj@ucw.cz> Cc: aleksey_gorelov@phoenix.com Signed-off-by: Lee Jones <lee.jones@linaro.org> Link: https://lore.kernel.org/r/20200702144625.2533530-3-lee.jones@linaro.org Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2020-07-03usb: phy: phy: Fix-up a whole bunch of formatting issuesLee Jones
Kerneldoc expects arg descriptions to be in the format '@.*: '. If either the '@' or the ':' is omitted then kerneldoc complains that the description is missing. Add the missing ':'s here. Also provide a new description for 'event'.

The PMC mux-agent can be used also to enter USB4 mode. The mux-agent does not have USB4 specific message, but it can be put into the TBT3 alternate mode also with USB4. That is OK because the controller is in any case the same with TBT3 and USB4.
