+* Superpix SP250A MIPI CSI-2 sensor
+
+Required Properties:
+- compatible: should be "superpix,sp250a".
+- clocks: reference to the 24M xvclk input clock.
+- clock-names: should be "xvclk".
+- power-domains: should be "power RK3568_PD_VI" for RK356x.
+- dovdd-supply: Digital I/O voltage supply, 1.8/2.8 volts
+- avdd-supply: Analog voltage supply, 2.8 volts
+- reset-gpios: High active reset gpio
+- pwdn-gpios: High active power-down gpio
+
+The device node must contain one 'port' child node for its digital output
+video port, and this port must have a single endpoint in accordance with
+ the video interface bindings defined in
+Documentation/devicetree/bindings/media/video-interfaces.txt.
+
+Endpoint node required properties for CSI-2 connection are:
+- remote-endpoint: a phandle to the bus receiver's endpoint node.
+- data-lanes: should be set to <1> (one CSI-2 lane supported).
+
+Example:

+	status = "okay";
