What would the semantics of a generic dma_wait_for_transfer() be?
I just don't see how this is generic at all, whatever the name.
Hm. It would be a check if the given DMA channel is active - and if it is busy waiting for it.
So, what would then be a generic interface for DMA? I see that this is a verrry basic solution - but where do you see the actual problems implementing this interface for other DMA controllers? Or do you think that the interface is to simple?
A whole new driver is IMHO not the right thing as there is too much duplicated code then.
So factor the common bits out into a separate file.
I haven't given up on the general solution yet. If I don't see another way I will do that.
