ARM:mvebu (CM-A510), add sound support using TLV320AIC23 audio-codec Message-ID: <54EB8D34.7040003@gmail.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Hello, I am trying to set the sound system using "simple-audio-card" and TLV320AIC23B audio codec in Compulab CM-510 SoM. This is my structure in DT, according to ./KERNEL/Documentation/devicetree/bindings/sound/simple-card.txt, /KERNEL/Documentation/devicetree/bindings/sound/widgets.txt and the source code of the audio-codec ./KERNEL/sound/soc/codecs/tlv320aic23.c : sound { compatible = "simple-audio-card"; simple-audio-card,name = "OnboardTLV320AIC23B"; simple-audio-card,format = "i2s"; simple-audio-card,bitclock-master = <&dailink_master>; simple-audio-card,frame-master = <&dailink_master>; simple-audio-card,widgets = "Microphone", "Mic Input", "Line", "Line Input", "Line", "Line Out", "Speaker", "Speaker", "Headphone", "Headphone Jack"; simple-audio-card,routing = "Line Out", "LOUT", "Line Out", "ROUT", "Line Out", "RHPOUT", "Line Out", "LHPOUT", "LLINEIN","Line Input", "RLINEIN","Line Input", "MICIN","Mic Input"; simple-audio-card,cpu { sound-dai = <&audio0 0>; }; dailink_master: simple-audio-card,codec { sound-dai = <&opt_audio>; }; }; }; /* TLV320AIC23 */ &opt_audio { status = "okay"; #sound-dai-cells= <0>; }; And this is the kernel trace: ... tlv320aic23-codec 0-001a: Control not supported for path LLINEIN -> [NULL] -> Line Input tlv320aic23-codec 0-001a: ASoC: no dapm match for LLINEIN --> NULL --> Line Input tlv320aic23-codec 0-001a: ASoC: Failed to add route LLINEIN -> NULL -> Line Input tlv320aic23-codec 0-001a: Control not supported for path RLINEIN -> [NULL] -> Line Input tlv320aic23-codec 0-001a: ASoC: no dapm match for RLINEIN --> NULL --> Line Input tlv320aic23-codec 0-001a: ASoC: Failed to add route RLINEIN -> NULL -> Line Input tlv320aic23-codec 0-001a: Control not supported for path MICIN -> [NULL] -> Mic Input tlv320aic23-codec 0-001a: ASoC: no dapm match for MICIN --> NULL --> Mic Input tlv320aic23-codec 0-001a: ASoC: Failed to add route MICIN -> NULL -> Mic Input usb 2-1.2: new high-speed USB device number 3 using orion-ehci asoc-simple-card sound: tlv320aic23-hifi <-> i2s mapping ok ...

Anyone has faced a similar problem? I would really appreciate some kind of help. Thank you, Gabriel
