IOMMU mappings take a prot parameter, identifying the protection bits
to enforce on the newly created mapping (READ or WRITE). The ARM
dma-mapping framework currently just passes 0 as the prot argument,
resulting in faulting mappings.

This patch infers the protection attributes based on the direction of
the DMA transfer.

Thanks for fixing this issue. Could I take this patch to my dma-mapping tree
with other dma-mapping changes I've collected recently or do you want my ack
and push it via other tree?

Please, feel free to take it via the dma-mapping tree! That's probably the
best route for it and there's nothing that really depends on it anyway.

Cheers,

Will
