Subject: [PATCH v7 1/6] iommu/arm-smmu: Pass io-pgtable config to implementation specific function
Date: Thu, 4 Jun 2020 14:57:05 -0600 [thread overview]
Message-ID: <20200604205710.3167-2-jcrouse@codeaurora.org> (raw)
In-Reply-To: <20200604205710.3167-1-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.
