Subject: [PATCH v2 04/15] iommu: Add DOMAIN_ATTR_PTBASE
Date: Tue, 21 May 2019 10:13:52 -0600 [thread overview]
Message-ID: <1558455243-32746-5-git-send-email-jcrouse@codeaurora.org> (raw)
In-Reply-To: <1558455243-32746-1-git-send-email-jcrouse@codeaurora.org>
Add an attribute to return the base address of the pagetable. This is used
by auxiliary domains from arm-smmu to return the address of the pagetable
to the leaf driver so that it can set the appropriate pagetable through
it's own means.
