+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>;
+ };
+ };
+ };
+ };
