current I use IMX6ULL, I meat a SPI DMA issue.

I configated SPI as POL=0, PHA=1. When I use SPI polling to do data transfer, then it is OK.

But when I use SPI DMA to do data transfer,  then the SPI timing look like POL=0, PHA=0. 

what is wrong with it? is there something wrong configuration while in SPI DMA or in SPI DMA, IMX6ULL only support POL=0, PHA=0?
