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.
|
||
|
|
|
||
|

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
|
||
|
|
- link-frequencies: List of allowed data link frequencies. An array of
|
||
|
|
64-bit elements.
|
||
|
|
|
||
|
|
|
||
|
|
Optional properties
|
||
|
|
-------------------
|
||
|
|
|
||
|
|
- nokia,nvm-size: The size of the NVM, in bytes. If the size is not given,
|
||
|
|
the NVM contents will not be read.
|
||
|
|
- 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
|
||
|
|
----------------------------------
|
||
|
|
|
||
|
|
- clock-lanes: <0>
|
||
|
|
- data-lanes: <1..n>
|
||
|
|
- remote-endpoint: A phandle to the bus receiver's endpoint node.
