USB: serial: cp210x: fix CP2102N-A01 modem control

2021-06-16T10:05:10+00:00

commit 63a8eef70ccb5199534dec56fed9759d214bfe55 upstream. CP2102N revision A01 (firmware version <= 1.0.4) has a buggy flow-control implementation that uses the ulXonLimit instead of ulFlowReplace field of the flow-control settings structure (erratum CP2102N_E104). A recent change that set the input software flow-control limits incidentally broke RTS control for these devices when CRTSCTS is not set as the new limits would always enable hardware flow control. Fix this by explicitly disabling flow control for the buggy firmware versions and only updating the input software flow-control limits when IXOFF is requested. This makes sure that the terminal settings matches the default zero ulXonLimit (ulFlowReplace) for these devices.

USB: serial: cp210x: fix alternate function for CP2102N QFN20

2021-06-16T10:05:10+00:00

commit 6f7ec77cc8b64ff5037c1945e4650c65c458037d upstream. The QFN20 part has a different GPIO/port function assignment. The configuration struct bit field ordered as TX/RX/RS485/WAKEUP/CLK which exactly matches GPIO0-3 for QFN24/28. However, QFN20 has a different GPIO to primary function assignment. Special case QFN20 to follow to properly detect which GPIOs are available.

USB: serial: quatech2: fix control-request directions

2021-06-16T10:05:09+00:00

commit eb8dbe80326c3d44c1e38ee4f40e0d8d3e06f2d0 upstream. The direction of the pipe argument must match the request-type direction bit or control requests may fail depending on the host-controller-driver implementation. Fix the three requests which erroneously used usb_rcvctrlpipe().

commit ea7ada4de2f7406150dd35ecd0302842587a464e upstream. The XR21V141X does not have a 5- or 6-bit mode, but the current implementation failed to properly restore the old setting when CS5 or CS6 was requested. Instead an invalid request would be sent to the device.
