Subject: [RESEND PATCH 0/4] iommu: add qcom_iommu for early "B" family devices
Date: Wed, 9 Aug 2017 10:43:01 -0400 [thread overview]
Message-ID: <20170809144310.22855-1-robdclark@gmail.com> (raw)
An iommu driver for Qualcomm "B" family devices which do implement the
ARM SMMU spec, but not in a way that arm-smmu can support.
(I initially added support to arm-smmu, but it was decided that approach
was too intrusive and it would be cleaner to have a separate driver.)
I should note that all the dependencies for this driver have been merged
since 4.12, and it is the last thing needed for having another fully-
enabled (gpu/display/video codec/etc) ARM device that is fully upstream.
These patches can also be found at:
git://people.freedesktop.org/~robclark/linux qcom_iommu-next
https://cgit.freedesktop.org/~robclark/linux/log/?h=qcom_iommu-next
No change since last time.
