[alsa-devel] How to set TWL4030 to Option2

[Lopez Cruz, Misael]

I'm adding the voice dai to sdp3430 machine driver, but the codec's
"twl4030_voice_startup" function has a requirement for voice to work: the
codec has to be in option2. How can I switch the codec to option2 mode?
There is no control for doing that, and the only way I see is to
directly modify the reg cache, but I assume that is not the right way
to do it.

Could you please clarify?
