Cover letter [PATCH 0/4] Miscellaneous ARM SMMU patches
Quoted 5 lines · Robin Murphy

Here's my current "miscellaneous SMMU enhancements" branch for your consideration. Patch #1 solves a subtle corner case that cropped up while exercising stage 1 context formats on the DMA330-MMU500 model; #3 will be wanted fairly soon for DMA ops integration so may as well get some exposure now; #2 and #4 are more nice-to-haves.

Cheers, Robin. I've queued #1 and #3 for 4.6. If you address the comments on the other two, I can queue those as well.
