Subject: media: dt-bindings: media: i2c: Add mono version to IMX290 bindings
X-Git-Tag: v6.4-rc1~161^2~395
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=f8d5f7d9e11a414204e011808043e2c0fb6aacae;p=thirdparty%2Fkernel%2Flinux.git

media: dt-bindings: media: i2c: Add mono version to IMX290 bindings

The IMX290 module is available as either monochrome or colour and
the variant is not detectable at runtime.

Add a new compatible string for the monochrome version, based on the
full device name IMX290LLR. For consistency, add a new compatible string
for the colour version based on the IMX290LQR full device name, and
deprecate the current ambiguous compatible string.

 description: |-
   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.
