Hi, The Renesas IDT821034 codec is four channel PCM codec with on-chip filters and programmable gain setting. It also provides SLIC (Subscriber Line Interface Circuit) signals as GPIOs. Based on previous iteration: https://lore.kernel.org/all/20230111134905.248305-1-herve.codina@xxxxxxxxxxx/ the bigger change is the codec driver rework in order to remove the regmap virtual registers layer. Best regards, Herve Codina Changes v1 -> v2: - All patches Reformat commit log - Patch 1 Remove '$ref: /schemas/gpio/gpio.yaml#' Use 'unevaluatedProperties: false' Update the node name and remove the sound node in the example - Patch 2 Change the file header comment format Rework in order to remove the regmap virtual registers Herve Codina (3): dt-bindings: sound: Add Renesas IDT821034 codec ASoC: codecs: Add support for the Renesas IDT821034 codec MAINTAINERS: add the Renesas IDT821034 codec entry .../bindings/sound/renesas,idt821034.yaml | 75 ++ MAINTAINERS | 7 + sound/soc/codecs/Kconfig | 12 + sound/soc/codecs/Makefile | 2 + sound/soc/codecs/idt821034.c | 1200 +++++++++++++++++ 5 files changed, 1296 insertions(+) create mode 100644 Documentation/devicetree/bindings/sound/renesas,idt821034.yaml create mode 100644 sound/soc/codecs/idt821034.c -- 2.39.0
