    Subject[PATCH 04/68] serial: add UART_CAP_EFR and UART_CAP_SLEEP flags to 16C950 UARTs definition
    Date
    From: Yegor Yefremov <yegor_sub1@visionsystems.de>

    Adding UART_CAP_EFR and UART_CAP_SLEEP flags will enable sleep mode
    and automatic CTS flow control for 16C950 UARTs. It will also avoid
    capabilities detection warning like this:

    "ttyS0: detected caps 00000700 should be 00000100"
