Please use scripts/get_maintainers.pl to get a list of necessary people and lists to CC. It might happen, that command when run on an older kernel, gives you outdated entries.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: Maso Huang <maso.huang@mediatek.com> > --- > .../sound/mediatek,mt79xx-wm8960.yaml | 53 +++++++++++++++++++ > 1 file changed, 53 insertions(+) > create mode 100644 Documentation/devicetree/bindings/sound/mediatek,mt79xx-wm8960.yaml > > diff --git a/Documentation/devicetree/bindings/sound/mediatek,mt79xx-wm8960.yaml b/Documentation/devicetree/bindings/sound/mediatek,mt79xx-wm8960.yaml > new file mode 100644 > index 000000000000..26b38bb629da > --- /dev/null > +++ b/Documentation/devicetree/bindings/sound/mediatek,mt79xx-wm8960.yaml > @@ -0,0 +1,53 @@ > +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) > +%YAML 1.2 > +--- > +$id: http://devicetree.org/schemas/sound/mediatek,mt79xx-wm8960.yaml# > +$schema: http://devicetree.org/meta-schemas/core.yaml# > + > +title: MediaTek MT79xx ASOC sound card with WM8960 codec What is a MT79xx ASOC?

I have no clue what is "ALSA SoC" (as SoC means System on Chip). Please describe real hardware not Linux or your configuration or some SW. Best regards, Krzysztof
