Is there any way to run an event when power up/down a snd_soc_dapm_kcontrol type widgt? Because we need to do something with mute/unmute headphone. e.g. rt5640_pmu_depop is what we need when unmute headphone. We need to set something before and after set the hp mute bit.
If there is an event to do that, it will be easier to implement that.
You can setup a event for the SND_SOC_DAPM_SWITCH, but this will run after setting the mute bit and before clearing the mute bit.
