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@...ia.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...
