Subject: [PATCH v17 12/20] iommu/arm-smmu: Pass io-pgtable config to implementation specific function
Date: Sat, 5 Sep 2020 13:04:18 -0700 [thread overview]
Message-ID: <20200905200454.240929-13-robdclark@gmail.com> (raw)
In-Reply-To: <20200905200454.240929-1-robdclark@gmail.com>
From: Jordan Crouse <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.
