Subject: [PATCH] media: dt-bindings: Convert imx290.txt to YAML
|
|
|
|
Upstream commit a96dfea1df25
|
|
|
|
Convert the Sony IMX290 DT binding from text to YAML. Add Manivannan as
|
|
a maintainer given that he is listed in MAINTAINERS for the file, as
|
|
volunteering myself.
|
|
|
|
The name of the input clock, "xclk", is wrong as the hardware manual
|
|
names it INCK. As the device has a single clock, the name could be
|
|
omitted, but that would require a corresponding change to the driver and
|
|
is thus a candidate for further patches.

-* 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
|
