What's the cell-index in these nodes used to index? Given the
confusion there's been about the proper use of this property, a
comment indicating which shared registers this is used to index is
probably a good idea.
There's supposed to be a cell-index in the *channels* to index into
the
shared summary register (the "reg" of the dma node itself). I don't
see any
purpose for a cell-index in the main dma node, though.
I believe this comes into play when we have more than one DMA
controller and sometimes there are special uses like on 8610.
There is no need to guess what it is or isn't used for. Just look
it up in the binding for this device.
