SMIA++, defined by Nokia, is an extension +of that. These definitions are valid for both types of sensors. + +More detailed documentation can be found in +Documentation/devicetree/bindings/media/video-interfaces.txt . + +The device node should contain a "port" node which may contain one or more +endpoint nodes, in accordance with video interface bindings defined in +Documentation/devicetree/bindings/media/video-interfaces.txt . + +Mandatory properties +-------------------- + +- compatible: "nokia,smia" +- reg: I2C address (0x10, or an alternative address) +- vana-supply: Analogue voltage supply (VANA), typically 2,8 volts (sensor + dependent). +- clocks: External clock to the sensor +- clock-frequency: Frequency of the external clock to the sensor +- link-frequencies: List of allowed data link frequencies.
