+Intersil ISL7998x BT656-to-MIPI-CSI2 decoder
+
+The Intersil ISL7998x is a BT656-to-MIPI-CSI decoder which, capable of
+receiving up to four analog stream and multiplexing them into up to four
+MIPI CSI2 virtual channels, using one MIPI clock lane and 1/2 data lanes.
+
+Required Properties:
+- compatible: value should be "isil,isl79987"
+- pd-gpios: a GPIO spec for the Power Down pin (active high)
+
+Option Properties:
+- isil,num-inputs: Number of connected inputs (1, 2 or 4)
+
+For further reading on port node refer to
+Documentation/devicetree/bindings/media/video-interfaces.txt.
+
+Example:
+
+	i2c_master {
+		isl7998x_mipi@44 {
+			compatible = "isil,isl79987";
+			reg = <0x44>;
+			isil,num-inputs = <4>;
+			pinctrl-names = "default";
+			pinctrl-0 = <&pinctrl_videoadc>;
+			pd-gpios = <&gpio3 27 GPIO_ACTIVE_HIGH>;
+			status = "okay";
+
+			port {
+				isl79987_to_mipi_csi2: endpoint {
+					remote-endpoint = <&mipi_csi2_in>;
+					clock-lanes = <0>;
+					data-lanes = <1 2>;
+				};
+			};
+		};
+	};
