The Google Chameleon v3 is a device made for testing audio and video paths of other devices. This patchset adds support for ASoC audio on this device. It has two audio sources: HDMI audio from the it68051 chip (RX only), and analog audio from the ssm2603 chip (RX and TX). The patchset adds the ASoC platform and codec drivers, as well as some changes to the existing ssm2602 codec driver. v2 changes: * Replace chv3-audio machine driver with simple-audio-card * Use regmap_register_patch() in ssm2602 workaround * Remove ssm2602 mute gpio patch, add a gpio hog instead * Simplify hw_pointer logic in chv3-i2s * Commit splits & other misc changes Paweł Anikiel (7): ASoC: Add Google Chameleon v3 i2s driver ASoC: Add Google Chameleon v3 codec driver ASoC: dt-bindings: Add Google Chameleon v3 i2s device ASoC: dt-bindings: Add Google Chameleon v3 audio codec ARM: dts: chameleonv3: Add mute gpio hog ARM: dts: chameleonv3: Add Chameleon v3 audio ASoC: ssm2602: Add workaround for playback distortions .../bindings/sound/google,chv3-codec.yaml | 31 ++ .../bindings/sound/google,chv3-i2s.yaml | 44 +++ .../boot/dts/socfpga_arria10_chameleonv3.dts | 62 ++++ sound/soc/Kconfig | 1 + sound/soc/Makefile | 1 + sound/soc/codecs/Kconfig | 8 + sound/soc/codecs/Makefile | 2 + sound/soc/codecs/chv3-codec.c | 41 +++ sound/soc/codecs/ssm2602.c | 15 + sound/soc/google/Kconfig | 6 + sound/soc/google/Makefile | 2 + sound/soc/google/chv3-i2s.c | 338 ++++++++++++++++++ 12 files changed, 551 insertions(+) create mode 100644 Documentation/devicetree/bindings/sound/google,chv3-codec.yaml create mode 100644 Documentation/devicetree/bindings/sound/google,chv3-i2s.yaml create mode 100644 sound/soc/codecs/chv3-codec.c create mode 100644 sound/soc/google/Kconfig create mode 100644 sound/soc/google/Makefile create mode 100644 sound/soc/google/chv3-i2s.c -- 2.40.1.521.gf1e218fcd8-goog
