Apologies, but my original email bounced for Andy and Heikki,

I suppose this one, i.e. commit dd4e91d538b3 ("dmaengine: slave means at
least one of DMA_SLAVE, DMA_CYCLIC"), solves the issue.

Hmm...that commit didn't seem to fix my issue.

In regard to Peter's reply:

"The error is that your dmaengine driver doesn't support the functionality
required by the 8250 driver."

Does this mean that the 8250_dw.c driver can no longer use DMA?
