The devices have an integrated DSP and load diagnostics, and are controlled over I2C. Patch 1 adds the dt-binding, patch 2 the codec driver, patch 3 the ALSA mixer controls documentation, and patch 4 adds the MAINTAINERS entry. Tested on AM62D-EVM with a TAS67CD-AEC daughter card, on setups & test procedures, refer to the Github repository. GitHub: https://github.com/SenWang125/tas67-linux Changes in v2: - Remove redundant DAPM event function (2/4) - Move IRQ request past power_on, so regs can be set in a clean state (2/4) - Add delayed_work at probe time to accomdate no PM configs (2/4) - Change .set_fmt and .dapm_routes callbacks to the same tas675x_set_fmt name (1/3) - Links to v1: https://lore.kernel.org/all/20260401024210.28542-1-sen@ti.com/ Sen Wang (4): dt-bindings: sound: Add ti,tas675x ASoC: codecs: Add TAS675x quad-channel audio amplifier driver Documentation: sound: Add TAS675x codec mixer controls documentation MAINTAINERS: add entry for TAS675x audio amplifier .../devicetree/bindings/sound/ti,tas675x.yaml | 278 +++ Documentation/sound/codecs/index.rst | 1 + Documentation/sound/codecs/tas675x.rst | 618 +++++ MAINTAINERS | 4 + sound/soc/codecs/Kconfig | 12 + sound/soc/codecs/Makefile | 2 + sound/soc/codecs/tas675x.c | 2158 +++++++++++++++++ sound/soc/codecs/tas675x.h | 367 +++ 8 files changed, 3440 insertions(+) create mode 100644 Documentation/devicetree/bindings/sound/ti,tas675x.yaml create mode 100644 Documentation/sound/codecs/tas675x.rst create mode 100644 sound/soc/codecs/tas675x.c create mode 100644 sound/soc/codecs/tas675x.h -- 2.43.0
