Simply one or two register settings can enable them to work. Init for these chips are hardware reset or software reset. As to some audio filter params for internal filters, it is up to the special user cases, which can be saved into the bin file. The default value also can work well. --- .../devicetree/bindings/sound/ti,pcm6240.yaml | 276 ++++++++++++++++++ 1 file changed, 276 insertions(+) create mode 100644 Documentation/devicetree/bindings/sound/ti,pcm6240.yaml diff --git a/Documentation/devicetree/bindings/sound/ti,pcm6240.yaml b/Documentation/devicetree/bindings/sound/ti,pcm6240.yaml new file mode 100644 index 000000000000..f06264d81b46 --- /dev/null +++ b/Documentation/devicetree/bindings/sound/ti,pcm6240.yaml @@ -0,0 +1,276 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +# Copyright (C) 2022 -
