Can't we come up with a version of dma_request_slave_channel that works
both ways for now:

	mcspi_dma->dma_rx =
		dma_request_slave_channel_compat(mask, omap_dma_filter_fn, &sig,
					&master->dev, mcspi_dma->dma_rx_ch_name);
	...			

Then it's just question of patching away two lines later on rather than
having to add all this if else to all the drivers first, then patching
it away again.

I think that something like that is workable with the implementation
simply checking for of_node to do the right thing.

Yes, I think it would be better to have common API but underneath two
implementations in transitional phase.

Ok, I'll implement something for discussion in the v2 series.
