2009-09-23USB-serial: pl2303: use 1.5 instead of 2 stop bits with 5 data bitsFrank Schaefer
This is how "real" UARTs (e.g. 16550) work and AFAIK what RS232 specifies, too. Make the driver more compliant. Signed-off-by: Frank Schaefer <schaefer.frank@gmx.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2009-09-23USB-serial: pl2303: fix baud rate handling in case of unsupported valuesFrank Schaefer
According to the datasheets, the PL2303 supports a set of 25 baudrates. The baudrate is set as a 4 byte value directly. During my experiments with device 067b:2303 (PL2303X), I noticed that - the bridge-controller always uses 9600 baud if invalid/unsupported baud rate values are set - the baud rate value returned by usb_control_msg(..., GET_LINE_REQUEST, ...) does not reflect the actually used baudrate. Always the last set value is returned, even if it was invalid and not used by the controller. This patch fixes the following issues with the current code: 1.) make sure that only supported baudrates are set (are there any buggy chip revisions out there which don't "like" other values... ?). 2.) always set the baudrate to the next nearest supported baudrate. 3.) applications can now read back the resulting baudrate properly, because tty_encode_baud_rate(...) is now fed with the actually used baudrate.

2009-08-07USB: pl2303: New vendor and product idKhanh-Dang Nguyen Thu Lam
I am submitting a patch for the pl2303 driver. This patch adds support for the "Sony QN-3USB" cable (vendor=0x054c, product=0x0437). This USB cable is a so-called data cable used to connect a Sony mobile phone to a computer. Supported models are Sony CMD-J5, J6, J7, J16, J26, J70 and Z7. I have used this patch with my Sony CMD-J70 for several days and I haven't encountered any kernel/hardware issue.

2009-07-12USB: pl2303: New vendor and product id for the prolific driverGianpaolo Cugola
I recently bought a PC interface for the Cressi Edy dive computer (www.cressi.it) and discovered that it uses the pl2303 chip, albeit with ad-hoc vendor and product ids (04b8, 0521 respectively). Being in the process of writing a linux software for such device (cressi only provides a windows software), I patched the pl2303 linux driver to have the interface recognized. I am submitting you the patch (very basic) for inclusion in next kernel version. From: Gianpaolo Cugola <gianpaoloc@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2009-06-16USB: usb-serial: replace shutdown with disconnect, releaseAlan Stern
This patch (as1254) splits up the shutdown method of usb_serial_driver into a disconnect and a release method. The problem is that the usb-serial core was calling shutdown during disconnect handling, but drivers didn't expect it to be called until after all the open file references had been closed. The result was an oops when the close method tried to use memory that had been deallocated by shutdown.

2008-10-13tty: usb-serial krefsAlan Cox
Use kref in the USB serial drivers so that we don't free tty structures from under the URB receive handlers as has historically been the case if you were unlucky.

2008-10-13usb: fix pl2303 initializationJason Wessel
This patch removes the private check for the termios_initialized for the pl2303 usb driver. It forced the baud to 9600 on the first call to pl2303_set_termios() Based on the tty changes in the 2.6.27 kernel, the termios passed to the *_set_termios functions is always populated the first time. This means there is no need to privately initialize the settings the first time, and doing so will not allow the use of the kernel parameter "console=ttyUSB0,115200" as an example.

2008-07-22usb_serial: API all changeAlan Cox
USB serial likes to use port->tty back pointers for the real work it does and to do so without any actual locking. Unfortunately when you consider hangup events, hangup/parallel reopen or even worse hangup followed by parallel close events the tty->port and port->tty pointers are not guaranteed to be the same as port->tty is the active tty while tty->port is the port the tty may or may not still be attached to. So rework the entire API to pass the tty struct. For console cases we need to pass both for now. This shows up multiple drivers that immediately crash with USB console some of which have been fixed in the process. Longer term we need a proper tty as console abstraction Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2008-01-09pl2303: Fix mode switching regressionAlan Cox
Cleaning out all the incorrect 'no change made' checks for termios settings showed up a problem with the PL2303. The hardware here seems to lose sync and bits if you tell it to make no changes. This shows up with a real world application. To fix this the driver check for meaningful hardware changes is restored but doing the tests correctly and as a tty layer function so it doesn't get duplicated wrongly everywhere if other drivers turn out to need it.

This is the grungy swap all the occurrences in the right places patch that goes with the updates. At this point we have the same functionality as before (except that sgttyb() returns speeds not zero) and are ready to begin turning new stuff on providing nobody reports lots of bugs If you are a tty driver author converting an out of tree driver the only impact should be termios->ktermios name changes for the speed/property setting functions from your upper layers. If you are implementing your own TCGETS function before then your driver was broken already and its about to get a whole lot more painful for you so please fix it 8) Also fill in c_ispeed/ospeed on init for most devices, although the current code will do this for you anyway but I'd like eventually to lose that extra paranoia [akpm@osdl.org: bluetooth fix] [mp3@de.ibm.com: sclp fix] [mp3@de.ibm.com: warning fix for tty3270] [hugh@veritas.com: fix tty_ioctl powerpc build] [jdike@addtoit.com: uml: fix ->set_termios declaration] Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Martin Peschke <mp3@de.ibm.com> Acked-by: Peter Oberparleiter <oberpar@de.ibm.com> Cc: Cornelia Huck <cornelia.huck@de.ibm.com> Signed-off-by: Hugh Dickins <hugh@veritas.com> Signed-off-by: Jeff Dike <jdike@addtoit.com> Cc: Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
