Subject: [PATCH v3 00/14] iommu: Permit modular builds of ARM SMMU[v3] drivers
Date: Thu, 21 Nov 2019 11:49:04 +0000 [thread overview]
Message-ID: <20191121114918.2293-1-will@kernel.org> (raw)
Hi everyone,
This is version three of the patches I previously posted here:
v1: https://lore.kernel.org/lkml/20191030145112.19738-1-will@kernel.org/
v2: https://lore.kernel.org/lkml/20191108151608.20932-1-will@kernel.org
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.
Will
