Re: [alsa-devel] [PATCH] ASoC: add RT5677 CODEC driver

...

+static int rt5677_set_micbias1_event(struct snd_soc_dapm_widget *w,

• struct snd_kcontrol *kcontrol, int event) {
• struct snd_soc_codec *codec = w->codec;
• struct rt5677_priv *rt5677 = snd_soc_codec_get_drvdata(codec);
• switch (event) {
• case SND_SOC_DAPM_POST_PMU:

• regmap_update_bits(rt5677->regmap, RT5677_PWR_ANLG2,
  

• 	RT5677_PWR_CLK_MB1 | RT5677_PWR_PP_MB1 |
  

• 	RT5677_PWR_CLK_MB, RT5677_PWR_CLK_MB1 |
  

• 	RT5677_PWR_PP_MB1 | RT5677_PWR_CLK_MB);
  

What does this do - I note we never undo this?

We will add a PMD case for this event, thanks.
