Subject: [PATCH] media: dt-bindings: media: i2c: Add IMX290 CMOS
|
||
|
|
sensor binding
|
||
|
|
|
||
|
|
Commit 8a97a4676f8b1badcd9cfbed2b081342847bb1b1 upstream.
|
||
|
|
|
||
|
|
Add devicetree binding for IMX290 CMOS image sensor. Let's also
|
||
|
|
add MAINTAINERS entry for the binding and driver.

+* Sony IMX290 1/2.8-Inch CMOS Image Sensor
|
||
|
|
+
|
||
|
|
+The Sony IMX290 is a 1/2.8-Inch CMOS Solid-state image sensor with
|
||
|
|
+Square Pixel for Color Cameras. It is programmable through I2C and 4-wire
|
||
|
|
+interfaces. The sensor output is available via CMOS logic parallel SDR output,
|
||
|
|
+Low voltage LVDS DDR output and CSI-2 serial data output. The CSI-2 bus is the
|
||
|
|
+default. No bindings have been defined for the other busses.
|
||
|
|
+
|
||
|
|
+Required Properties:
|
||
|
|
+- compatible: Should be "sony,imx290"
|
||
|
|
+- reg: I2C bus address of the device
|
||
|
|
+- clocks: Reference to the xclk clock.
|
||
|
|
+- clock-names: Should be "xclk".
|
||
|
|
+- clock-frequency: Frequency of the xclk clock in Hz.
|
||
|
|
+- vdddo-supply: Sensor digital IO regulator.
|
||
|
|
+- vdda-supply: Sensor analog regulator.
|
||
|
|
+- vddd-supply: Sensor digital core regulator.
|
||
|
|
+
|
||
|
|
+Optional Properties:
|
||
|
|
+- reset-gpios: Sensor reset GPIO
|
||
|
|
+
|
||
|
|
+The imx290 device node should contain one 'port' child node with
|
||
|
|
+an 'endpoint' subnode. For further reading on port node refer to
|
||
|
|
+Documentation/devicetree/bindings/media/video-interfaces.txt.
|
||
|
|
+
|
||
|
|
+Required Properties on endpoint:
|
||
|
|
+- data-lanes: check ../video-interfaces.txt
|
||
|
|
+- link-frequencies: check ../video-interfaces.txt
|
||
|
|
+- remote-endpoint: check ../video-interfaces.txt
