[alsa-devel] asoc: how to enable micbias and codec power when headset inserted

[Babu, Ramesh]

Hi

I have question on handling mic bias and codec bias when headset is inserted.
When headset is inserted, the mic bias and codec bias should be ON, in order to get the
button press interrupts from the headset.

Do I need to have dapm path to achieve this?  
Reference to existing code would be nice !

Regards
Ramesh
