A nit, subject: drop second/last, redundant "dt sche,a". The "dt-bindings" prefix is already stating that these are bindings/dt schema. See also: https://elixir.bootlin.com/linux/v6.7-rc8/source/Documentation/devicetree/bindings/submitting-patches.rst#L18 And subject is neither correct nor complete. You did not add here SM8550 SoC, but SM8550 Iris. Plus what is SM8550? TI SM8550? Samsung SM8550? You have entire commit subject to say briefly such details without repeating obvious "dt schema". > > Signed-off-by: Dikshita Agarwal <quic_dikshita@xxxxxxxxxxx> > --- > .../bindings/media/qcom,sm8550-iris.yaml | 162 +++++++++++++++++++++ > 1 file changed, 162 insertions(+) > > diff --git a/Documentation/devicetree/bindings/media/qcom,sm8550-iris.yaml b/Documentation/devicetree/bindings/media/qcom,sm8550-iris.yaml > new file mode 100644 > index 000000000000..a7aa6a6190cf > --- /dev/null > +++ b/Documentation/devicetree/bindings/media/qcom,sm8550-iris.yaml > @@ -0,0 +1,162 @@ > +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) > +%YAML 1.2 > +--- > +$id: http://devicetree.org/schemas/media/qcom,sm8550-iris.yaml# > +$schema: http://devicetree.org/meta-schemas/core.yaml# > + > +title: Qualcomm IRIS video encode and decode accelerators IRIS or Iris?
