Re: [alsa-devel] [PATCH] ASoC: TWL4030: Add tristate callbacks for HiFi and Voice

Add "set_tristate" callbacks for HiFi and Voice DAIs. Machine drivers can enable and disable tristate for each DAI with "snd_soc_dai_set_tristate" function provided by SoC core.

+static int twl4030_set_tristate(struct snd_soc_dai *dai, int tristate) +{

• struct snd_soc_codec *codec = dai->codec;
• u8 reg = twl4030_read_reg_cache(codec, TWL4030_REG_VOICE_IF);

I think you wanted to read the TWL4030_REG_AUDIO_IF register here...

• if (tristate)

• reg |= TWL4030_AIF_TRI_EN;
  

• else

• reg &= ~TWL4030_AIF_TRI_EN;
  

• return twl4030_write(codec, TWL4030_REG_AUDIO_IF, reg);
