I think by adding 'dma-channel' property is there to enable the DMA mode via DT.
As for stripping out the DMA support: I'm fine with that if no one objects,
but in the header of the file we have:
* Author: Jarkko Lavinen <jarkko.lavinen@nokia.com> and Juha Yrjölä
* IRQ and DMA support written by Timo Teras
So I believe the DMA and IRQ code was a big stunt itself to receive it's own
line there...
