| |
Hi all,
This is version two of the patches I previously posted here:
https://lore.kernel.org/lkml/20191030145112.19738-1-will@kernel.org/
Changes since v1 include:
* Build single "arm-smmu-mod.ko" module for the Arm SMMU driver * Hold a reference to the IOMMU driver module across {add,remove}_device() * Take a reference to the IOMMU driver module during of_xlate() * Added Bjorn's ack on the PCI export patch
Please note that I haven't been able to test this properly, since I don't currently have access to any Arm SMMU hardware.
Cheers,
Will
