    Subject[PATCH 03/11] serial: bfin_5xx: IRDA is not affected by anomaly 05000230
    Date
    From: Graf Yang <graf.yang@analog.com>

    Anomaly 05000230 (over sampling of the UART STOP bit) applies only when
    the peripheral is operating in UART mode. So drop the anomaly handling
    when the UART is in IRDA mode.
