Another idea would be to remove the filter function from struct dma_chan_map and pass the map through platform data
Why not unified device properties?
Is this some Windows/ACPI feature?
Nope.
Check drivers/base/property.c
Quick search gives mostly MSDN and Windows10 related links.
We only need dma_chan_map for platforms which has not been converted to DT and still using legacy boot. Or platforms which can still boot in legacy mode. In DT/ACPI mode we do not need this map at all.
