2021-03-17USB: serial: ch341: add new Product IDNiv Sardi1-0/+1
commit 5563b3b6420362c8a1f468ca04afe6d5f0a8d0a3 upstream. Add PID for CH340 that's found on cheap programmers. The driver works flawlessly as soon as the new PID (0x9986) is added to it. These look like ANU232MI but ship with a ch341 inside. They have no special identifiers (mine only has the string "DB9D20130716" printed on the PCB and nothing identifiable on the packaging. The merchant i bought it from doesn't sell these anymore). the lsusb -v output is: Bus 001 Device 009: ID 9986:7523 Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 1.10 bDeviceClass 255 Vendor Specific Class bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 8 idVendor 0x9986 idProduct 0x7523 bcdDevice 2.54 iManufacturer 0 iProduct 0 iSerial 0 bNumConfigurations 1 Configuration Descriptor: bLength 9 bDescriptorType 2 wTotalLength 0x0027 bNumInterfaces 1 bConfigurationValue 1 iConfiguration 0 bmAttributes 0x80 (Bus Powered) MaxPower 96mA Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 0 bAlternateSetting 0 bNumEndpoints 3 bInterfaceClass 255 Vendor Specific Class bInterfaceSubClass 1 bInterfaceProtocol 2 iInterface 0 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x82 EP 2 IN bmAttributes 2 Transfer Type Bulk Synch Type None Usage Type Data wMaxPacketSize 0x0020 1x 32 bytes bInterval 0 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x02 EP 2 OUT bmAttributes 2 Transfer Type Bulk Synch Type None Usage Type Data wMaxPacketSize 0x0020 1x 32 bytes bInterval 0 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x81 EP 1 IN bmAttributes 3 Transfer Type Interrupt Synch Type None Usage Type Data wMaxPacketSize 0x0008 1x 8 bytes bInterval 1 Signed-off-by: Niv Sardi <xaiki@evilgiggle.com> Cc: stable@vger.kernel.org Signed-off-by: Johan Hovold <johan@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

commit 979d9cbe75b922ab1695b8ad5576115774f72e62 upstream. The latest chip family (HXN) apparently does not support setting the line speed using divisors and instead needs to use the direct encoding scheme for all rates. This specifically enables 50, 110, 134, 200 bps and other rates not supported by the original chip type.

2021-03-04USB: serial: option: update interface mapping for ZTE P685MLech Perczak1-1/+2
commit 6420a569504e212d618d4a4736e2c59ed80a8478 upstream. This patch prepares for qmi_wwan driver support for the device. Previously "option" driver mapped itself to interfaces 0 and 3 (matching ff/ff/ff), while interface 3 is in fact a QMI port. Interfaces 1 and 2 (matching ff/00/00) expose AT commands, and weren't supported previously at all. Without this patch, a possible conflict would exist if device ID was added to qmi_wwan driver for interface 3. Update and simplify device ID to match interfaces 0-2 directly, to expose QCDM (0), PCUI (1), and modem (2) ports and avoid conflict with QMI (3), and ADB (4). The modem is used inside ZTE MF283+ router and carriers identify it as such. Interface mapping is: 0: QCDM, 1: AT (PCUI), 2: AT (Modem), 3: QMI, 4: ADB T: Bus=02 Lev=02 Prnt=02 Port=05 Cnt=01 Dev#= 3 Spd=480 MxCh= 0 D: Ver= 2.01 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1 P: Vendor=19d2 ProdID=1275 Rev=f0.00 S: Manufacturer=ZTE,Incorporated S: Product=ZTE Technologies MSM S: SerialNumber=P685M510ZTED0000CP&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&0 C:* #Ifs= 5 Cfg#= 1 Atr=a0 MxPwr=500mA I:* If#= 0 Alt= 0 #EPs= 2 Cls=ff(vend.)

commit 320f9028c7873c3c7710e8e93e5c979f4c857490 upstream. The driver did not update its view of the available device buffer space until write() was called in task context. This meant that write_room() would return 0 even after the device had sent a write-unthrottle notification, something which could lead to blocked writers not being woken up (e.g. when using OPOST). Note that we must also request an unthrottle notification is case a write() request fills the device buffer exactly.

2020-12-30USB: serial: keyspan_pda: fix dropped unthrottle interruptsJohan Hovold1-2/+2
commit 696c541c8c6cfa05d65aa24ae2b9e720fc01766e upstream. Commit c528fcb116e6 ("USB: serial: keyspan_pda: fix receive sanity checks") broke write-unthrottle handling by dropping well-formed unthrottle-interrupt packets which are precisely two bytes long. This could lead to blocked writers not being woken up when buffer space again becomes available. Instead, stop unconditionally printing the third byte which is (presumably) only valid on modem-line changes.

commit 5098e77962e7c8947f87bd8c5869c83e000a522a upstream. The driver must not call tty_wakeup() while holding its private lock as line disciplines are allowed to call back into write() from write_wakeup(), leading to a deadlock. Also remove the unneeded work struct that was used to defer wakeup in order to work around a possible race in ancient times (see comment about n_tty write_chan() in commit 14b54e39b412 ("USB: serial: remove changelogs and old todo entries")).

This is a partial revert of commit 2bb70f0a4b23 ("USB: serial: option: support dynamic Quectel USB compositions") The Quectel BG96 is different from most other modern Quectel modems, having serial functions with 3 endpoints using ff/ff/ff and ff/fe/ff class/subclass/protocol. Including it in the change to accommodate dynamic function mapping was incorrect. Revert to interface number matching for the BG96, assuming static layout of the RMNET function on interface 4. This restores support for the serial functions on interfaces 2 and 3.
