    I'm not sure...this is rather platform-specific, so I don't think it
    really belongs in the atmel_serial() driver. One solution might be to
    add a function pointer to struct atmel_uart_data that the driver can
    call from ->suspend() in order to let the platform code handle this as
    appropriate.

    Cc'ing Andrew Victor and David Brownell since they know the AT91
    platform code better than me.
