+title: Himax HM5065 CSI camera sensor
+
+description: |+
+  At least one of reset-gpios and enable-gpios must be configured.
+
+  The device node must contain one 'port' child node for its digital output
+  video port, in accordance with the video interface bindings defined in
+  
+  Documentation/devicetree/bindings/media/video-interfaces.txt.
