* | USB: pl2303: fix data corruption on termios updatesJohan Hovold2014-01-031-9/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some PL2303 devices are known to lose bytes if you change serial settings even to the same values as before. Avoid this by comparing the encoded settings with the previsouly used ones before configuring the device. The common case was fixed by commit bf5e5834bffc6 ("pl2303: Fix mode switching regression"), but this problem was still possible to trigger, for instance, by using the TCSETS2-interface to repeatedly request 115201 baud, which gets mapped to 115200 and thus always triggers a settings update.

* USB: pl2303: fixed handling of CS5 settingColin Leitner2013-12-021-16/+14
| | | | | | | | | | | | | | | This patch fixes the CS5 setting on the PL2303 USB-to-serial devices. CS5 has a value of 0 and the CSIZE setting has been skipped altogether by the enclosing if. Tested on 3.11.6 and the scope shows the correct output after the fix has been applied. Tagged to be added to stable, because it fixes a user visible driver bug and is simple enough to backport easily.

* USB: ftdi_sio: fixed handling of unsupported CSIZE settingColin Leitner2013-12-021-13/+24
| | | | | | | | | | | | | | | | | | | | | | | | FTDI UARTs support only 7 or 8 data bits. Until now the ftdi_sio driver would only report this limitation for CS6 to dmesg and fail to reflect this fact to tcgetattr. This patch reverts the unsupported CSIZE setting and reports the fact with less severance to dmesg for both CS5 and CS6. To test the patch it's sufficient to call stty -F /dev/ttyUSB0 cs5 which will succeed without the patch and report an error with the patch applied. As an additional fix this patch ensures that the control request will always include a data bit size.

* USB: serial: fix race in generic writeJohan Hovold2013-11-251-9/+1
| | | | | | | | | | | | | | | | | | | Fix race in generic write implementation, which could lead to temporarily degraded throughput. The current generic write implementation introduced by commit 27c7acf22047 ("USB: serial: reimplement generic fifo-based writes") has always had this bug, although it's fairly hard to trigger and the consequences are not likely to be noticed. Specifically, a write() on one CPU while the completion handler is running on another could result in only one of the two write urbs being utilised to empty the remainder of the write fifo (unless there is a second write() that doesn't race during that time).

* USB: pl2303: distinguish between original and cloned HX chipsFrank Schäfer2013-09-171-11/+32
| | | | | | | | | | | | | | | | | | | | | | | According to Prolific, several (unauthorized) cheap and less functional clones of the PL2303HX chip are in circulation. [1] I've had the chance to test such a cloned device and it turned out that it doesn't support any baud rates above 115200 baud (original: 6 Mbaud) It also doesn't support the divisior based baud rate encoding method, so no continuous baud rate adjustment is possible. Nevertheless, these devices have been working (unintentionally) with the driver up to commit 61fa8d694b ("pl2303: also use the divisor based baud rate encoding method for baud rates < 115200 with HX chips"), and this commit broke support for them. Fortunately, it is pretty simple to distinguish between the original and the cloned HX chips, so I've added a check and an extra chip type to keep the clones working. The same check is used by the latest Prolific Windows driver, so it should be solid.

Note: ftdi_sio.c still has a DEVICE_ATTR() used, that will have to wait until after 3.12-rc1 comes out when DEVICE_ATTR_WO() shows up in Linus's tree.
