2015-09-21USB: pl2303: fix baud-rate divisor calculationsMichał Pecio
commit 49bda21266fdf195142e8b5dea057f09e96ada9f upstream. This commit fixes the following issues: 1. The 9th bit of buf was believed to be the LSB of divisor's exponent, but the hardware interprets it as MSB (9th bit) of the mantissa. The exponent is actually one bit shorter and applies to base 4, not 2 as previously believed. 2. Loop iterations doubled the exponent instead of incrementing. 3. The exponent wasn't checked for overflow. 4. The function returned requested rate instead of actual rate. Due to issue #2, the old code deviated from the wrong formula described in #1 and actually yielded correct rates when divisor was lower than 4096 by using exponents of 0, 2 or 4 base-2, interpreted as 0, 1, 2 base-4 with the 9th mantissa bit clear. However, at 93.75 kbaud or less the rate turned out too slow due to #2 or too fast due to #2 and #3. I tested this patch by sending and validating 0x00,0x01,..,0xff to an FTDI dongle at 234, 987, 2401, 9601, 31415, 115199, 250k, 500k, 750k, 1M, 1.5M, 3M+1 baud. All rates passed. I also used pv to check speed at some rates unsupported by FTDI: 45 (the lowest possible), 2M, 4M, 5M and 6M-1. Looked sane.

commit 951d3793bbfc0a441d791d820183aa3085c83ea9 upstream. The driver used usb_get_serial_data(port->serial) which compiled but resulted in a NULL pointer being returned (and subsequently used). I did not go deeper into this but I guess this is a regression.

2015-08-16USB: qcserial/option: make AT URCs work for Sierra Wireless MC7305/MC7355Reinhard Speyerer
commit 653cdc13a340ad1cef29f1bab0d05d0771fa1d57 upstream. Tests with a Sierra Wireless MC7355 have shown that 1199:9041 devices also require the option_send_setup() code to be used on the USB interface for the AT port to make unsolicited response codes work correctly. Move these devices from the qcserial driver to the option driver like it has been done for the 1199:68c0 devices in commit d80c0d14183516f184a5ac88e11008ee4c7d2a2e ("USB: qcserial/option: make AT URCs work for Sierra Wireless MC73xx").

commit 74472233233f577eaa0ca6d6e17d9017b6e53150 upstream. Add support for the Sierra Wireless AR8550 device with USB descriptor 0x1199, 0x68AB. It is common with MC879x modules 1199:683c/683d which also are composite devices with 7 interfaces (0..6) and also MDM62xx based as the AR8550. The major difference are only the interface attributes 02/02/01 on interfaces 3 and 4 on the AR8550. They are vendor specific ff/ff/ff on MC879x modules. lsusb reports: Bus 001 Device 004: ID 1199:68ab Sierra Wireless, Inc.

2015-04-29USB: visor: Match I330 phone more preciselyJason A. Donenfeld
Samsung has just released a portable USB3 SSD, coming in a very small and nice form factor. It's USB ID is 04e8:8001, which unfortunately is already used by the Palm Visor driver for the Samsung I330 phone cradle. Having pl2303 or visor pick up this device ID results in conflicts with the usb-storage driver, which handles the newly released portable USB3 SSD. To work around this conflict, I've dug up a mailing list post [1] from a long time ago, in which a user posts the full USB descriptor information. The most specific value in this appears to be the interface class, which has value 255 (0xff). Since usb-storage requires an interface class of 0x8, I believe it's correct to disambiguate the two devices by matching on 0xff inside visor.

This patch also implement DTR/RTS control when baudrate B0. We drop DTR/RTS when B0, otherwise enable it. We are checking baudrate in set_termios() too, If baudrate larger then 115200, it will be changed to 115200 and use tty_encode_baud_rate() to encode into tty Signed-off-by: Peter Hung <hpeter+linux_kernel@gmail.com> Signed-off-by: Johan Hovold <johan@kernel.org>

2015-03-02USB: ch341: set tty baud speed according to tty structNicolas PLANEL
The ch341_set_baudrate() function initialize the device baud speed according to the value on priv->baud_rate. By default the ch341_open() set it to a hardcoded value (DEFAULT_BAUD_RATE 9600). Unfortunately, the tty_struct is not initialized with the same default value. (usually 56700) This means that the tty_struct and the device baud rate generator are not synchronized after opening the port. Fixup is done by calling ch341_set_termios() if tty exist. Remove unnecessary variable priv->baud_rate setup as it's already done by ch341_port_probe(). Remove unnecessary call to ch341_set_{handshake,baudrate}() in ch341_open() as there already called in ch341_configure() and ch341_set_termios() Signed-off-by: Nicolas PLANEL <nicolas.planel@enovance.com> Signed-off-by: Johan Hovold <johan@kernel.org>
