We do not expect to receive spurious interrupts so rise a warning
if it happens.
RX overrun is an error condition that signals a corrupted RX
stream both in dma and in irq modes. Report the error and
abort the transfer in either cases.

Ensure that messages given to transfer_one handler can actually be
handled by it. For that purpose rely on the SPI framework

Defer the probe operation when a reset controller device is expected
but have not yet been probed.
This change replaces use of devm_reset_control_get_exclusive() with
devm_reset_control_get_optional_exclusive() as reset controller is
optional which is now explicitly stated.

On 0 byte transfer request, return straight from the

The digital filter related computation are present in the driver
however the programming of the filter within the IP is missing.
The maximum value for the DNF is wrong and should be 15 instead of 16.
