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.

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 .

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.

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)
