Subject: [PATCH v3 05/16] iommu: Add DOMAIN_ATTR_PTBASE
Date: Wed, 29 May 2019 14:54:41 -0600	[thread overview]
Message-ID: <1559163292-4792-6-git-send-email-jcrouse@codeaurora.org> (raw)
In-Reply-To: <1559163292-4792-1-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.
