Sherry Sun bbadf50383 tty: serial: fsl_lpuart: disable transmitter before changing RS485 related registers ... [ Upstream commit f5cb528d6441eb860250a2f085773aac4f44085e ] According to the LPUART reference manual, TXRTSE and TXRTSPOL of MODIR register only can be changed when the transmitter is disabled. So disable the transmitter before changing RS485 related registers and re-enable it after the change is done.
