The binding looks ok, but the wording is slightly incorrect here:
strictly speaking, it's not a pair of controller phandle and request
line number, but a DMA descriptor as specified in bindings/dma/dma.txt
with a format specific to the dma engine being used. That can
require more than just a single integer request number.
