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

11Mandatory properties
12--------------------
13
14- compatible: "nokia,smia"
15- reg: I2C address (0x10, or an alternative address)
16- vana-supply: Analogue voltage supply (VANA), typically 2,8 volts (sensor
17  dependent).
18- clocks: External clock to the sensor
19- clock-frequency: Frequency of the external clock to the sensor
20- link-frequencies: List of allowed data link frequencies. An array of
21  64-bit elements.
22
23
24Optional properties
25-------------------
26
27- nokia,nvm-size: The size of the NVM, in bytes. If the size is not given,
28  the NVM contents will not be read.
29- reset-gpios: XSHUTDOWN GPIO
30- flash-leds: See ../video-interfaces.txt
31- lens-focus: See ../video-interfaces.txt
32- rotation: Integer property; valid values are 0 (sensor mounted upright)
33	    and 180 (sensor mounted upside down). See
34	    ../video-interfaces.txt .

37Endpoint node mandatory properties
38----------------------------------
39
40- clock-lanes: <0>
41- data-lanes: <1..n>
42- remote-endpoint: A phandle to the bus receiver's endpoint node.
