* USB: pl2303: fix data corruption on termios updatesJohan Hovold2014-04-021-8/+25
| | | | | | | | | | | | | | | | | | | | | commit 623c8263376c0b8a4b0c220232e7313d762cd0cc upstream. 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 Leitner2014-01-031-17/+14
| | | | | | | | | | | | | | | | | | | commit a313249937820f8b1996133fc285efbd6aad2c5b upstream. 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.

Through many times to test, ch341 works well with this device, and pl2303 doesn't work quite often(it just work quite little). ch341 works well with this device, so we doesn't need pl2303 to support.I try to revert 026dfaf1 first, but it failed.

| | | | | | | | | | | | | | | | | Alan's commit 335f8514f200e63d689113d29cb7253a5c282967 introduced .carrier_raised function in several drivers. That also means tty_port_block_til_ready can now suspend the process trying to open the serial port when Carrier Detect is low and put it into tty_port.open_wait queue. We need to wake up the process when Carrier Detect goes high and trigger TTY hangup when CD goes low. Some of the devices do not report modem status line changes, or at least we don't understand the status message, so for those we remove .carrier_raised again.

| | | | | | | | | | | | | | | | | | | | | | 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.
