Can we clean it all up? I would bet that the msm_reset() is there because we changed the buad rate and so if we remove the baud rate setting we can remove the reset as well (see commit a12f1b406f2d tty: serial: msm: Reset uartdm after baud rate change, 2014-10-29). We might as well dump the CR_CMD_PROTECTION_EN and CR_TX_ENABLE thing as well given that we do the same in msm_set_baud_rate() already. And maybe we can even get rid of the baud rate capping and forced 8N1 setting that goes on here too.
