I tested it on the Nokia N= 900 and was able to play sound with aplay using earphones and earspeaker. T= he Loudspeakers did not work. I don't know the reason. The patchset consists of 4 patches: 1. convert rx51-audio to snd_soc_register_card() 2. init audio in rx51 platform file 3. add some DT helpers to ASoC core 4. add DT support to rx51-audio Please note, that the patch is RFC level for now. For example non DT bo= ot does not work, because I did not yet add pdata in boardcode. Proposed DTS node would look like this: sound: rx51-audio { compatible =3D "nokia,rx51-audio"; ti,mcbsp =3D <&mcbsp2>; ti,codec =3D <&tlv320aic3x>; ti,codec_aux =3D <&tlv320aic3x_aux>; ti,headset_amp =3D <&tpa6130a2>; tvout-selection-gpio =3D <&gpio2 8 GPIO_ACTIVE_HIGH>; /* 40 */ jack-detection-gpio =3D <&gpio6 17 GPIO_ACTIVE_HIGH>; /* 177 */ eci-sw-gpio =3D <&gpio6 22 GPIO_ACTIVE_HIGH>; /* 182 */ speaker-amp-gpio =3D <&twl_gpio 7 GPIO_ACTIVE_HIGH>; }; -- Sebastian Pali Roh=C3=A1r (2): ASoC: omap: rx51: Use snd_soc_register_card ARM: OMAP: rx51: Register audio device Sebastian Reichel (2): ASoC: Allow Aux Codecs to be specified using DT ASoC: RX-51: Add DT support to sound driver .../devicetree/bindings/sound/nokia,rx51.txt | 28 +++ .../devicetree/bindings/vendor-prefixes.txt | 1 + arch/arm/mach-omap2/board-rx51-peripherals.c | 11 ++ include/sound/rx51.h | 18 ++ include/sound/soc.h | 13 +- sound/soc/omap/omap-mcbsp.c | 5 +- sound/soc/omap/omap-mcbsp.h | 2 +- sound/soc/omap/rx51.c | 212 +++++++++++++= ++------ sound/soc/soc-core.c | 68 +++++-- 9 files changed, 277 insertions(+), 81 deletions(-) create mode 100644 Documentation/devicetree/bindings/sound/nokia,rx51.= txt create mode 100644 include/sound/rx51.h --=20 1.8.4.rc3
