[ARM] 3444/1: i.MX: Scatter-gather DMA emulation for i.MX/MX1 ...
Patch from Pavel Pisa
This patch contains simplified set of changes to add scatter-gather
emulation capability into MX1 DMA support. The result should
be still usable for next combination of DMA transfers
Statter-Gather/linear/2D/FIFO to linear/2D/FIFO and
linear/2D/FIFO to Statter-Gather/2D/FIFO
The patch corrects channel priority allocation to be compatible
with MX1 hardware implementation.
Previous code has not been adapted from its PXA original.
