Please use scripts/get_maintainers.pl to get a list of necessary people and lists to CC (and consider --no-git-fallback argument). It might happen, that command when run on an older kernel, gives you outdated entries. Therefore please be sure you base your patches on recent Linux kernel. > > Signed-off-by: Umang Jain <umang.jain@xxxxxxxxxxxxxxxx> > --- > .../bindings/media/i2c/sony,imx519.yaml | 113 ++++++++++++++++++ A nit, subject: drop second/last, redundant "DT bindings". The "dt-bindings" prefix is already stating that these are bindings. > 1 file changed, 113 insertions(+) > create mode 100644 Documentation/devicetree/bindings/media/i2c/sony,imx519.yaml > > diff --git a/Documentation/devicetree/bindings/media/i2c/sony,imx519.yaml b/Documentation/devicetree/bindings/media/i2c/sony,imx519.yaml > new file mode 100644 > index 000000000000..6f38b09890d2 > --- /dev/null > +++ b/Documentation/devicetree/bindings/media/i2c/sony,imx519.yaml > @@ -0,0 +1,113 @@ > +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) > +%YAML 1.2 > +--- > +$id: http://devicetree.org/schemas/media/i2c/imx519.yaml# Please test. > +$schema: http://devicetree.org/meta-schemas/core.yaml# > + > +title: Sony 1/2.5-Inch 16Mpixel CMOS Digital Image Sensor > + > +maintainers: > + - Lee Jackson <lee.jackson@xxxxxxxxxxx> > + > +description: |- > + The Sony IMX519 is a 1/2.5-inch CMOS active pixel digital image sensor > + with an active array size of 4656H x 3496V.

Open existing bindings, e.g. imx219, 258 or any other and look. Please, do not write patches entirely different than all other drivers/bindings.
