1 SMIA/SMIA++ sensor
2
3 SMIA (Standard Mobile Imaging Architecture) is an image sensor standard
4 defined jointly by Nokia and ST. SMIA++, defined by Nokia, is an extension
5 of that. These definitions are valid for both types of sensors.

7 More detailed documentation can be found in
8 Documentation/devicetree/bindings/media/video-interfaces.txt .
9
10 The device node should contain a "port" node which may contain one or more
11 endpoint nodes, in accordance with video interface bindings defined in
12 Documentation/devicetree/bindings/media/video-interfaces.txt .

14 Mandatory 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).
