I've now asked Guennadi to rework his DMAC DT v4 series and include a
subset of these patches. These ones look fine, but I'd like to have
them together with the DMAC DT bits to get the full picture if
possible. I'm a bit hesitant with moving the SHDMA_SLAVE_xx bits into
drivers/ when they are not going to be used by DT anyway.

Cheers,
