USB: serial: cp210x: disable break signalling on CP2105 SCI

2023-06-07T15:00:23Z

Only the first UART interface (ECI) on CP2105 supports break signalling. Return an error on requests for break state changes for the second interface (SCI) to avoid transmitting a garbage character and waiting when break is not supported. Tested-by: Corey Minyard Signed-off-by: Johan Hovold

USB: serial: return errors from break handling

2023-06-07T15:00:23Z

Start propagating errors to user space when setting the break state fails. This will be used by follow-on changes to also report when a driver or device does not support break control. Tested-by: Corey Minyard Signed-off-by: Johan Hovold

USB: serial: cp210x: add Silicon Labs IFS-USB-DATACABLE IDs

2023-03-13T15:01:13Z

The Silicon Labs IFS-USB-DATACABLE is used in conjunction with for example the Quint UPSes. It is used to enable Modbus communication with the UPS to query configuration, power and battery status. Signed-off-by: Kees Jan Koster Cc: stable@vger.kernel.org Signed-off-by: Johan Hovold

USB: serial: cp210x: add support for B0 hangup

2022-11-30T06:37:12Z

A request to set the line speed to B0 is used to hang up a modem connection by deasserting the modem control lines. Note that there is no need reconfigure the line speed in hardware when B0 is requested (even if some drivers do set it to an arbitrary value for implementation or protocol reasons).

USB: serial: cp210x: add Kamstrup RF sniffer PIDs

2022-11-28T09:36:50Z

The RF sniffers are based on cp210x where the RF frontends are based on a different USB stack. RF sniffers can analyze packets meta data including power level and perform packet injection. Can be used to perform RF frontend self-test when connected to a concentrator, ex. arch/arm/boot/dts/imx7d-flex-concentrator.dts Signed-off-by: Bruno Thomsen Cc: stable@vger.kernel.org Signed-off-by: Johan Hovold
