Jean-Philippe Brucker	ed1d08b9d0	dt-bindings: Document stall property for IOMMU masters ... On ARM systems, some platform devices behind an IOMMU may support stall, which is the ability to recover from page faults. Let the firmware tell us when a device supports stall.

Thierry Reding	1a5b537644	devicetree: Add generic IOMMU device tree bindings ... This commit introduces a generic device tree binding for IOMMU devices. Only a very minimal subset is described here, but it is enough to cover the requirements of both the Exynos System MMU and Tegra SMMU as discussed here: https://lkml.org/lkml/2014/4/27/346 Acked-by: Will Deacon <will.deacon@arm.com> Reviewed-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Rob Herring <robh@kernel.org> Signed-off-by: Thierry Reding <treding@nvidia.com> Reviewed-by: Mark Rutland <mark.rutland@arm.com> Reviewed-by: Olof Johansson <olof@lixom.net> Acked-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Joerg Roedel <jroedel@suse.de>	2014-07-31 20:28:43 +02:00
