Subject: [PATCH v4 02/16] iommu/of: Request ACS from the PCI core when configuring IOMMU linkage
Date: Thu, 19 Dec 2019 12:03:38 +0000 [thread overview]
Message-ID: <20191219120352.382-3-will@kernel.org> (raw)
In-Reply-To: <20191219120352.382-1-will@kernel.org>
To avoid having to export 'pci_request_acs()' to modular IOMMU drivers,
move the call into the 'of_dma_configure()' path in a similar manner to
the way in which ACS is configured when probing via ACPI/IORT.
