+* 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.
