I would think that we need to keep this around so that the clock is actually enabled before we go and write to hardware registers. > if (options) > uart_parse_options(options, &baud, &parity, &bits, &flow); > > bits = 8; > parity = 'n'; > flow = 'n'; I wonder if we should leave this here? Maybe we can rely on the user specifying the right values on the command line? > - msm_write(port, UART_MR2_BITS_PER_CHAR_8 | UART_MR2_STOP_BIT_LEN_ONE, > - UART_MR2); /* 8N1 */ > - > - if (baud < 300 || baud > 115200) > - baud = 115200; > - msm_set_baud_rate(port, baud); > - > - msm_reset(port); > - > - if (msm_port->is_uartdm) { msm_port is unused now.
