    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.
    6 
    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 .
   13 
   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).
   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 
   27 Optional 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). See
   35             ../video-interfaces.txt .
   36 
   37 
   38 Endpoint node mandatory properties
   39 ----------------------------------
   40 
   41 - data-lanes: <1..n>
