Signed-off-by: Shenghao Ding --- Change in v2: - Rewrite the subject to match something similar to other commits. - And something to be compatible with. - minItems, then maxItems. - Drop reset-gpios description - Remove the repeated reg descriptions and reg constraints. - Drop redundant spaces. - Add missing line breaks between blocks and additionalProperties. - All these chips have only a portion of the functionality of codec, such as ADC or DAC, and so on, but their audio performance is far superior to the codec's, and cost is lower than codec, and much easier to program than codec. 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 -
