X-Git-Tag: v3.9-rc1~73 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f6c0ffa8f0b0781f4954cb06f0a81d6c10c1b434;p=profile%2Fivi%2Fkernel-adaptation-intel-automotive.git Merge tag 'iommu-updates-v3.9' of git://git./linux/kernel/git/joro/iommu Pull IOMMU Updates from Joerg Roedel: "Besides some fixes and cleanups in the code there are three more important changes to point out this time: * New IOMMU driver for the ARM SHMOBILE platform * An IOMMU-API extension for non-paging IOMMUs (required for upcoming PAMU driver) * Rework of the way the Tegra IOMMU driver accesses its registetrs - register windows are easier to extend now. There are also a few changes to non-iommu code, but that is acked by the respective maintainers." * tag 'iommu-updates-v3.9' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (23 commits) iommu/tegra: assume CONFIG_OF in SMMU driver iommu/tegra: assume CONFIG_OF in gart driver iommu/amd: Remove redundant NULL check before dma_ops_domain_free(). iommu/amd: Initialize device table after dma_ops iommu/vt-d: Zero out allocated memory in dmar_enable_qi iommu/tegra: smmu: Fix incorrect mask for regbase iommu/exynos: Make exynos_sysmmu_disable static ARM: mach-shmobile: r8a7740: Add IPMMU device ARM: mach-shmobile: sh73a0: Add IPMMU device ARM: mach-shmobile: sh7372: Add IPMMU device iommu/shmobile: Add iommu driver for Renesas IPMMU modules iommu: Add DOMAIN_ATTR_WINDOWS domain attribute iommu: Add domain window handling functions iommu: Implement DOMAIN_ATTR_PAGING attribute iommu: Check for valid pgsize_bitmap in iommu_map/unmap iommu: Make sure DOMAIN_ATTR_MAX is really the maximum iommu/tegra: smmu: Change SMMU's dependency on ARCH_TEGRA iommu/tegra: smmu: Use helper function to check for valid register offset iommu/tegra: smmu: Support variable MMIO ranges/blocks iommu/tegra: Add missing spinlock initialization ... --- f6c0ffa8f0b0781f4954cb06f0a81d6c10c1b434 diff --cc arch/arm/mach-exynos/mach-exynos5-dt.c index 973a066,2671075..acaeb14 --- a/arch/arm/mach-exynos/mach-exynos5-dt.c +++ b/arch/arm/mach-exynos/mach-exynos5-dt.c @@@ -103,12 -104,36 +103,42 @@@ static const struct of_dev_auxdata exyn OF_DEV_AUXDATA("samsung,mfc-v6", 0x11000000, "s5p-mfc-v6", NULL), OF_DEV_AUXDATA("samsung,exynos5250-tmu", 0x10060000, "exynos-tmu", NULL), + OF_DEV_AUXDATA("samsung,i2s-v5", 0x03830000, + "samsung-i2s.0", NULL), + OF_DEV_AUXDATA("samsung,i2s-v5", 0x12D60000, + "samsung-i2s.1", NULL), + OF_DEV_AUXDATA("samsung,i2s-v5", 0x12D70000, + "samsung-i2s.2", NULL), + OF_DEV_AUXDATA("samsung,exynos-sysmmu", 0x11210000, + "exynos-sysmmu.0", "mfc"), /* MFC_L */ + OF_DEV_AUXDATA("samsung,exynos-sysmmu", 0x11200000, + "exynos-sysmmu.1", "mfc"), /* MFC_R */ + OF_DEV_AUXDATA("samsung,exynos-sysmmu", 0x14650000, + "exynos-sysmmu.2", NULL), /* TV */ + OF_DEV_AUXDATA("samsung,exynos-sysmmu", 0x11F20000, + "exynos-sysmmu.3", "jpeg"), /* JPEG */ + OF_DEV_AUXDATA("samsung,exynos-sysmmu", 0x11D40000, + "exynos-sysmmu.4", NULL), /* ROTATOR */ + OF_DEV_AUXDATA("samsung,exynos-sysmmu", 0x13E80000, + "exynos-sysmmu.5", "gscl"), /* GSCL0 */ + OF_DEV_AUXDATA("samsung,exynos-sysmmu", 0x13E90000, + "exynos-sysmmu.6", "gscl"), /* GSCL1 */ + OF_DEV_AUXDATA("samsung,exynos-sysmmu", 0x13EA0000, + "exynos-sysmmu.7", "gscl"), /* GSCL2 */ + OF_DEV_AUXDATA("samsung,exynos-sysmmu", 0x13EB0000, + "exynos-sysmmu.8", "gscl"), /* GSCL3 */ + OF_DEV_AUXDATA("samsung,exynos-sysmmu", 0x13260000, + "exynos-sysmmu.9", NULL), /* FIMC-IS0 */ + OF_DEV_AUXDATA("samsung,exynos-sysmmu", 0x132C0000, + "exynos-sysmmu.10", NULL), /* FIMC-IS1 */ + OF_DEV_AUXDATA("samsung,exynos-sysmmu", 0x14640000, + "exynos-sysmmu.11", NULL), /* FIMD1 */ + OF_DEV_AUXDATA("samsung,exynos-sysmmu", 0x13C40000, + "exynos-sysmmu.12", NULL), /* FIMC-LITE0 */ + OF_DEV_AUXDATA("samsung,exynos-sysmmu", 0x13C50000, + "exynos-sysmmu.13", NULL), /* FIMC-LITE1 */ + OF_DEV_AUXDATA("samsung,exynos-sysmmu", 0x10A60000, + "exynos-sysmmu.14", NULL), /* G2D */ {}, };
