This "rx-tx" doesn't mean much but it could show that LocalPlus Bus FIFO
uses a single DMA read-write channel. Should I really drop it?

Hmmm, I'm not sure. Is there anything else (besides your driver) that parses this device tree node?

dma.txt says this:

"The specific strings that can be used are defined in the binding of the DMA client device."

So this looks like it's driver-specific, but it is a required property.
I guess you should keep it, but I think you should get a second opinion.
