+* Mediatek Digital Image Processor (DIP)
+
+Digital Image Processor (DIP) unit in Mediatek ISP system is responsible for
+image content adjustment according to the tuning parameters. DIP can process
+the image form memory buffer and output the processed image to multiple output
+buffers. Furthermore, it can support demosaicing and noise reduction on the
+images.
+
+Required properties:
+- compatible: "mediatek,mt8183-dip"
+- reg: Physical base address and length of the function block register space
+- interrupts: interrupt number to the cpu
+- iommus: should point to the respective IOMMU block with master port as
+  argument, see Documentation/devicetree/bindings/iommu/mediatek,iommu.txt
+  for details.
+- mediatek,larb: must contain the local arbiters in the current Socs, see
+  Documentation/devicetree/bindings/memory-controllers/mediatek,smi-larb.txt
+  for details.
+- clocks: must contain the local arbiters 5 (LARB5) and DIP clock
+- clock-names: must contain DIP_CG_IMG_LARB5 and DIP_CG_IMG_DIP
+
+Example:
+	dip: dip@15022000 {
+		compatible = "mediatek,mt8183-dip";
+		mediatek,larb = <&larb5>;
+		mediatek,mdp3 = <&mdp_rdma0>;
+		mediatek,vpu = <&vpu>;
+		iommus = <&iommu M4U_PORT_CAM_IMGI>;
+		reg = <0 0x15022000 0 0x6000>;
+		interrupts = <GIC_SPI 268 IRQ_TYPE_LEVEL_LOW>;
+		clocks = <&imgsys CLK_IMG_LARB5>,
+			 <&imgsys CLK_IMG_DIP>;
+		clock-names = "DIP_CG_IMG_LARB5",
+			      "DIP_CG_IMG_DIP";
+	};
