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>;
};
