That is why linux has been dropping the translation value portions of _DMA(). Since the emmc2 dma (with the old B0 SoC), and the dwc2 is expected to work, lets add matching 30 bit IORT entries for them. Finally, in the shuffle the high speed cap bit override was dropped from the linux patches, and I failed to add it back to the firmware values, this caused the wifi perf to be lower than it should have been.
