I've just followed devicetree/bindings/dma/dma.txt...
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.
