Well, I'm messing around with OMAP at the moment, converting its DMA
support to be DMA engine based.  As I think I've already said, I've
not taken _that_ much interest in dealing with how channels actually
get allocated there (though I do have something which works for the
time being so I can run and test this stuff.)

Note that the sa11x0 DMA engine driver uses strings to match channels,
and the strings are essentially identifiers for DMA request signals,
and this avoids either passing around DMA request numbers or having
them in some central header file.
