Subject: [PATCH] iommu/exynos: Select ARM_DMA_USE_IOMMU
Date: Fri, 4 Jul 2014 15:01:08 +0530 [thread overview]
Message-ID: <1404466268-9512-1-git-send-email-tushar.b@samsung.com> (raw)
For IOMMU to use on Exynos platforms, we need to enable ARM_DMA_USE_IOMMU. It
would be better to select it by default when EXYNOS_IOMMU is enabled.
