Subject: [PATCH] drm/exynos: IOMMU support should not be selectable by user
Date: Tue, 20 Jan 2015 15:31:14 +0100	[thread overview]
Message-ID: <1421764274-26398-1-git-send-email-m.szyprowski@samsung.com> (raw)

If system provides IOMMU feature, Exynos DRM should use it by default,
because the Exynos DRM subdrivers don't work correctly when Exynos IOMMU
driver has been enabled and no IOMMU support has been compiled into Exynos
DRM driver.
