The Marvell PXA SSP block is the same or similiar to the MMP2 variant.
The only difference in the binding is the PXA version supports DMA (and
that's probably a binding difference rather than an actual h/w
difference).
The old binding didn't belong under 'serial' as it is not a UART. The
SSP block also supports audio devices, so 'spi' is not a perfect fit
either. As the existing schema for MMP2 is there, just leave things
as-is.
The examples in the old text binding were pretty out of sync with
reality. 'clock-names' and 'ssp-id' aren't documented nor used.

Finally, reword a little bit the conditions to clarify what is intended

create a dirmap only on DATA_IN flows).

least one device on the market which ships with only 16-bit DMIC
configuration blob.
This corner case has never been supported and it is going to need topology
updates for DMIC copier to support multiple formats.
As for the kernel side: if the copier supports multiple formats and the
preferred 32-bit DMIC blob is not found then we will try to get a 16-bit
DMIC configuration and look for a 16-bit copier config.
