+* Mediatek seninf MIPI-CSI2 host driver
+
+Seninf MIPI-CSI2 host driver is a HW camera interface controller. It support a widely adopted,
+simple, high-speed protocol primarily intended for point-to-point image and video
+transmission between cameras and host devices.
+
+Required properties:
+  - compatible: "mediatek,mt8183-seninf"
+  - reg: Must contain an entry for each entry in reg-names.
+  - reg-names: Must include the following entries:
+    "base_reg": seninf registers base
+    "rx_reg": Rx analog registers base
+  - interrupts: interrupt number to the cpu.
+  - clocks : clock name from clock manager
+  - clock-names: must be CLK_CAM_SENINF and CLK_TOP_MUX_SENINF.
+    It is the clocks of seninf
+  - port : port for camera sensor
+  - port reg : must be '0' for camera 0, '1' for camera 1
+  - endpoint : config mipi-csi2 port setting for each camera
+  - data-lanes : the number of the data lane
+
+Example:
+    seninf: seninf@1a040000 {
+       compatible = "mediatek,mt8183_seninf";
+		reg = <0 0x1a040000 0 0x8000>,
+		      <0 0x11C80000 0 0x6000>;
+		reg-names = "base_reg", "ana_reg";
+		interrupts = <GIC_SPI 251 IRQ_TYPE_LEVEL_LOW>;
+		power-domains = <&scpsys MT8183_POWER_DOMAIN_CAM>;
+	    clocks =
+			<&camsys CLK_CAM_SENINF>, <&topckgen CLK_TOP_MUX_SENINF>;
+		clock-names =
+			"CLK_CAM_SENINF", "CLK_TOP_MUX_SENINF";
+		ports {
+			#address-cells = <1>;
+			#size-cells = <0>;
+			port@0 {
+				reg = <0>;
+				mipi_in_cam0: endpoint@0 {
+					reg = <0>;
+					data-lanes = <1 3>;
+				};
+			};
+			port@1 {
+				reg = <1>;
+				mipi_in_cam1: endpoint@0 {
+					reg = <1>;
+					data-lanes = <1 3>;
+				};
+			};
+		};
+	}
