There is also a lot of similarity between the mmci hardware and the
msm_sdcc hardware.  Enough so, that it is probably better for us to
make the mmci driver work with our hardware, rather than trying to
keep msm_sdcc going.

There is also an MSM nand device that appears to have not made it in.
It is heavily dependent on the weird features of the DMA hardware.  I
don't have any current plans to support this device, since most boards
using MSMs these days are using mmc/sd instead of bare NAND.

Our DMA hardware is really weird, but should be a bit reasonable.  It
is also being gradually replaced in newer chips with a different DMA
framework.

As far as I'm concerned, I consider making our DMA driver(s) use the
DMA engine API to be part of getting these platforms working with DT.

It is planned, but there are quite a few things that need to be
tackled first.

Ok, thanks for the information.
