3) TI may not have just one DMAC IP used in all the SoCs. So if you want

Yep unless we make it generic DMA_STRIDE_CONFIG simply, this makes
a lot of sense.

Okay, I can add one cmd for the EDMAC in DaVinci series of SoCs and
one for SDMAC in OMAP series of SoCs.

Wait, that's two different silicon blocks right? Then you already have proof
that this spans more than one DMAC and then you can just go for a generic
DMA_STRIDE_CONFIG from day one.

That both are TI does not matter, if they are totally unrelated implementations.
