No. See dma-ranges.
How exactly should I use dma-ranges? I can't find any other drivers
that queries that property and uses the result to call dma_set_mask. I
thought the dma-ranges property is intended to specify address
translation. I don't need to translate any address, I just need to know
a single number.
