Hi Bruce,

After bts test, we found out dma case failed. 
Because below commit is pushed into mainline kernel
66bdb1478fd1("swiotlb: Use dma_direct_supported() for swiotlb_ops")
But raspberrypi SDK kernel haven't done corresponding modification to compatible with mainline
There is only a Temporary fixing for DMA. So, I got it to fix the DMA initialization issue temporarily.

Could you please help to merge this patch into branch v5.2/standard/bcm-2xxx-rpi, linux-ycoto kernel.
