1SMIA/SMIA++ sensor 2 3SMIA (Standard Mobile Imaging Architecture) is an image sensor standard 4defined jointly by Nokia and ST. SMIA++, defined by Nokia, is an extension 5of that. These definitions are valid for both types of sensors. 6 7More detailed documentation can be found in 8Documentation/devicetree/bindings/media/video-interfaces.txt . 9 10The device node should contain a "port" node which may contain one or more 11endpoint nodes, in accordance with video interface bindings defined in 12Documentation/devicetree/bindings/media/video-interfaces.txt . 13 14Mandatory properties 15-------------------- 16 17- compatible: "nokia,smia" 18- reg: I2C address (0x10, or an alternative address) 19- vana-supply: Analogue voltage supply (VANA), typically 2,8 volts (sensor 20 dependent). 21- clocks: External clock to the sensor 22- clock-frequency: Frequency of the external clock to the sensor 23- link-frequencies: List of allowed data link frequencies. An array of 24 64-bit elements. 25 26 27Optional properties 28------------------- 29 30- reset-gpios: XSHUTDOWN GPIO 31- flash-leds: See ../video-interfaces.txt 32- lens-focus: See ../video-interfaces.txt 33- rotation: Integer property; valid values are 0 (sensor mounted upright) 34 and 180 (sensor mounted upside down).
