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 .
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.
Example
-------
&i2c2 {
clock-frequency = <400000>;
smiapp_1: camera@10 {
compatible = "nokia,smia";
reg = <0x10>;
reset-gpios = <&gpio3 20 0>;
vana-supply = <&vaux3>;
clocks = <&omap3_isp 0>;
clock-frequency = <9600000>;
nokia,nvm-size = <512>; /* 8 * 64 */
link-frequencies = /bits/ 64 <199200000 210000000 499200000>;
port {
smiapp_1_1: endpoint {
clock-lanes = <0>;
data-lanes = <1 2>;
remote-endpoint = <&csi2a_ep>;
};
};
};
};
