Subject: [PATCH 0/2] USB: DMA: point out recommend APIs
Although I submit these patches as the previous reply suggestion, I
am stilling wondering the IOMMU with USB controller. I think the most
of USB controller didn't need to create entities in IOMMU to support
scatterlist. Once the hcd supports that(sg_tablesize > 0), it could
support infinite scatter pages?
