Hi everyone, This is version three of the patches I previously posted here:
v1: https://lore.kernel.org/lkml/[email protected]/ v2: https://lore.kernel.org/lkml/[email protected] Changes since v2 include: * Tested successfully on real hardware (!) * Handle re-registering of IOMMU bus ops * Unregister IOMMU on unload * Prevent forced unbinding of SMMU drivers via sysfs * Update my email address in MODULE_AUTHOR Note that if you want to rely on the 'of_devlink' support in linux-next for dependent probe ordering, then you'll need an extra patch [1] to support PCI devices upstream of an SMMU. I'm routing that one via Greg.
