Erm, no it doesn't. My patch uses dma_request_slave_channel_compat() in
DT case, and that works fine with the current version of pdma, and
there's no need to read the "dmas" properties directly.

If you want to provide a way to simply denote the dma channel numbers,
without looking at the actual phandle, then yes, we could merge this
patch first, but it would be effectively reverted a proper implementation.
