| SMIA/SMIA++ sensor |
| |
| SMIA (Standard Mobile Imaging Architecture) is an image sensor standard |
| defined jointly by Nokia and ST. 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 |
| |
| |
| Optional properties |
| ------------------- |
| |
| - reset-gpios: XSHUTDOWN GPIO |
| - flash-leds: See ../video-interfaces.txt |
| - lens-focus: See ../video-interfaces.txt |
| - rotation: Integer property; valid values are 0 (sensor mounted upright) |
| and 180 (sensor mounted upside down). See |
| ../video-interfaces.txt . |
| |
| |
| Endpoint node mandatory properties |
| ---------------------------------- |
| |
| - data-lanes: <1..n> |
| - link-frequencies: List of allowed data link frequencies. An array of |
| 64-bit elements. |
| |
