* Revert "USB: serial: ch341: add new Product ID for CH341A"Dmytro Bagrii2022-02-211-1/+0
| | | | | | | | | | | | | | | | This reverts commit 46ee4abb10a07bd8f8ce910ee6b4ae6a947d7f63. CH341 has Product ID 0x5512 in EPP/MEM mode which is used for I2C/SPI/GPIO interfaces. In asynchronous serial interface mode CH341 has PID 0x5523 which is already in the table. Mode is selected by corresponding jumper setting.

* USB: serial: ch341: add support for GW Instek USB2.0-Serial devicesStephan Brunner2022-01-311-0/+1
| | | | | | | | | | | | | | | | | | Programmable lab power supplies made by GW Instek, such as the GPP-2323, have a USB port exposing a serial port to control the device. Stringing the supplied Windows driver, references to the ch341 chip are found. Binding the existing ch341 driver to the VID/PID of the GPP-2323 ("GW Instek USB2.0-Serial" as per the USB product name) works out of the box, communication and control is now possible. This patch should work with any GPP series power supply due to similarities in the product line.

* USB: serial: cp210x: fix CP2105 GPIO registrationJohan Hovold2021-12-141-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | When generalising GPIO support and adding support for CP2102N, the GPIO registration for some CP2105 devices accidentally broke. Specifically, when all the pins of a port are in "modem" mode, and thus unavailable for GPIO use, the GPIO chip would now be registered without having initialised the number of GPIO lines. This would in turn be rejected by gpiolib and some errors messages would be printed (but importantly probe would still succeed). Fix this by initialising the number of GPIO lines before registering the GPIO chip. Note that as for the other device types, and as when all CP2105 pins are muxed for LED function, the GPIO chip is registered also when no pins are available for GPIO use.

Note that the conversion of f81534a_ctrl_set_register() adds an extra an extra allocation and memcpy for every retry. Since this function is called rarely and retries are hopefully rare, the overhead should be acceptable.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some CP2102 do not support event-insertion mode but return no error when attempting to enable it. This means that any event escape characters in the input stream will not be escaped by the device and consequently regular data may be interpreted as escape sequences and be removed from the stream by the driver. The reporter's device has batch number DCL00X etched into it and as discovered by the SHA2017 Badge team, counterfeit devices with that marking can be detected by sending malformed vendor requests. [1][2] Tests confirm that the possibly counterfeit CP2102 returns a single byte in response to a malformed two-byte part-number request, while an original CP2102 returns two bytes. Assume that every CP2102 that behaves this way also does not support event-insertion mode (e.g. cannot report parity errors).
