* Aptina 1/4-Inch QXGA CMOS Digital Image Sensor
The Aptina MT9T111 is a 1/4-inch CMOS active pixel digital image sensor with
an active array size of 2048H x 1536V. It is programmable through a simple
two-wire serial interface.
Required Properties:
- compatible: value should be either one among the following
(a) "aptina,mt9t111" for MT9T111 color sensor
(b) "aptina,mt9t112" for MT9T112 color sensor
- input-clock-freq: Source clock freqquency (Hz)
- pixel-clock-freq: Target pixel clock freqquency (Hz)
Optional Properties:
- reset-gpios: Toggle when the module is enabled or disabled.
- powerdown-gpios: Toggle when the module is enabled or disabled.
- oscen-gpios: Enabled once at probe time.
- bufen-gpios: Enabled once at probe time.
- camen-gpios: Enabled once at probe time.
For further reading on port node refer to
Documentation/devicetree/bindings/media/video-interfaces.txt.
Example:
