Subject: [PATCH v11 01/12] iommu/arm-smmu: Pass io-pgtable config to implementation specific function
Date: Mon, 3 Aug 2020 13:35:36 -0600 [thread overview]
Message-ID: <20200803193547.305660-2-jcrouse@codeaurora.org> (raw)
In-Reply-To: <20200803193547.305660-1-jcrouse@codeaurora.org>
Construct the io-pgtable config before calling the implementation specific
init_context function and pass it so the implementation specific function
can get a chance to change it before the io-pgtable is created.
