Hi all, Here's an initial dump of what I've been doing for full generic binding support on SMMUv2. I'm posting it as one big series because it all fits together, but the OF and arm64 patches should be free to go through their respective trees without horribly breaking anything (I think...) Currently this just brings platform and PCI generic binding support to the level of the old binding, and adds proper group creation - I have more ongoing work on top of this to remove the stream ID limits and start filling in SMR support, which will probably show up added/folded in to subsequent revisions. I've put a branch together (based on the SMMU changes in -next) here: git://linux-arm.org/linux-rm iommu/generic Tested on Juno (MMU-401) and LS2085 (MMU-500) for both PCI and platform devices, plus various combinations of stream ID aliasing between the two. Since we don't yet have a robust solution for dealing with MSI doorbells downstream of translation, there are some temporary hacks that I've been running with on the iommu/msi branch.
