-Samsung Exynos IOMMU H/W, System MMU (System Memory Management Unit)
-
-Samsung's Exynos architecture contains System MMUs that enables scattered
-physical memory chunks visible as a contiguous region to DMA-capable peripheral
-devices like MFC, FIMC, FIMD, GScaler, FIMC-IS and so forth.
-
-System MMU is an IOMMU and supports identical translation table format to
-ARMv7 translation tables with minimum set of page properties including access
-permissions, shareability and security protection. In addition, System MMU has
-another capabilities like L2 TLB or block-fetch buffers to minimize translation
-latency.
-
-System MMUs are in many to one relation with peripheral devices, i.e. single
-peripheral device might have multiple System MMUs (usually one for each bus
-master), but one System MMU can handle transactions from only one peripheral
-device. The relation between a System MMU and the peripheral device needs to be
-defined in device node of the peripheral device.
-
-MFC in all Exynos SoCs and FIMD, M2M Scalers and G2D in Exynos5420 has 2 System
-MMUs.
-* MFC has one System MMU on its left and right bus.
-* FIMD in Exynos5420 has one System MMU for window 0 and 4, the other system MMU
-  for window 1, 2 and 3.
-* M2M Scalers and G2D in Exynos5420 has one System MMU on the read channel and
-  the other System MMU on the write channel.
-
-For information on assigning System MMU controller to its peripheral devices,
-see generic IOMMU bindings.
-
-Required properties:
-- compatible: Should be "samsung,exynos-sysmmu"
-- reg: A tuple of base address and size of System MMU registers.
-- #iommu-cells: Should be <0>.
-- interrupts: An interrupt specifier for interrupt signal of System MMU,
-	      according to the format defined by a particular interrupt
-	      controller.
-- clock-names: Should be "sysmmu" or a pair of "aclk" and "pclk" to gate
-	       SYSMMU core clocks.
-	       Optional "master" if the clock to the System MMU is gated by
-	       another gate clock other core  (usually main gate clock
-	       of peripheral device this SYSMMU belongs to).
-- clocks: Phandles for respective clocks described by clock-names.
-- power-domains: Required if the System MMU is needed to gate its power.
-	  Please refer to the following document:
-	  Documentation/devicetree/bindings/power/pd-samsung.txt
-
-Examples:
-	gsc_0: gsc@13e00000 {
-		compatible = "samsung,exynos5-gsc";
-		reg = <0x13e00000 0x1000>;
-		interrupts = <0 85 0>;
-		power-domains = <&pd_gsc>;
-		clocks = <&clock CLK_GSCL0>;
-		clock-names = "gscl";
-		iommus = <&sysmmu_gsc0>;
-	};
-
-	sysmmu_gsc0: sysmmu@13e80000 {
-		compatible = "samsung,exynos-sysmmu";
-		reg = <0x13E80000 0x1000>;
-		interrupt-parent = <&combiner>;
-		interrupts = <2 0>;
-		clock-names = "sysmmu", "master";
-		clocks = <&clock CLK_SMMU_GSCL0>, <&clock CLK_GSCL0>;
-		power-domains = <&pd_gsc>;
-		#iommu-cells = <0>;
-	};
