The "snps,data-width" property[1] defines the AXI data width of the DMA
controller as:
width = 8 × (2^n) bits
(0 = 8 bits, 1 = 16 bits, 2 = 32 bits, ..., 6 = 512 bits)
where "n" is the value of "snps,data-width".
For the CV18xx DMA controller, the correct AXI data width is 32 bits,
corresponding to "snps,data-width = 2".
Test results on Milkv Duo S can be found here [2].
