[RFC 0/4] DT support for rx51-audio

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

This patchset adds DT support in rx51-audio. I tested it on the Nokia N900
and was able to play sound with aplay using earphones and earspeaker. The
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 boot
does not work, because I did not yet add pdata in boardcode.

Proposed DTS node would look like this:

sound: rx51-audio {
       compatible = "nokia,rx51-audio";

       ti,mcbsp = <&mcbsp2>;
       ti,codec = <&tlv320aic3x>;
       ti,codec_aux = <&tlv320aic3x_aux>;
       ti,headset_amp = <&tpa6130a2>;

       tvout-selection-gpio = <&gpio2 8 GPIO_ACTIVE_HIGH>; /* 40 */
       jack-detection-gpio = <&gpio6 17 GPIO_ACTIVE_HIGH>; /* 177 */
       eci-sw-gpio = <&gpio6 22 GPIO_ACTIVE_HIGH>; /* 182 */
       speaker-amp-gpio = <&twl_gpio 7 GPIO_ACTIVE_HIGH>;
};
