The driver must provide throttle and unthrottle in uart_ops when it
sets UPSTAT_AUTORTS. Add them using existing stop_rx &
enable_interrupts functions.
Compile tested (w/o linking).

Maybe this one is the correct solution (I'm not able to test on the real
hw though)?
It seems that max310x suffers from the same issue but it doesn't have
an easy to use stop_rx available so it requires a bit more effort to
figure out how to actually do the throttle state.

Hi Nuno,
It seems I managed to put the .throttle and .unthrottle into the wrong
ops within amba-pl011.c. I'm sorry about the extra trouble. This patch has
a bit higher likelihood of doing something useful to the problem:
From: Ilpo Järvinen <ilpo.jarvinen@linux.intel.com>
[PATCH v3] serial: pl011: UPSTAT_AUTORTS requires .throttle/unthrottle
The driver must provide throttle and unthrottle in uart_ops when it

enable_interrupts functions.

The driver must provide throttle and unthrottle in uart_ops when it
sets UPSTAT_AUTORTS. Add them using existing stop_rx &
