[PATCH v2] serial: imx: warn user when using unsupported configuration

2018-04-18 Thread Stefan Agner
When using half-duplex mode (which disables receiver during txing) the RTS signal cannot be driven low during transmission. This seems to be a limitation of the i.MX UART IP: The RTS (CTS_B) signal is controlled by the receiver. When the receiver is disabled, the signal stays in UART logic idle
