Hi Andreas,

After looking at your patch more carefully, I see that most of the
change is subject to the new "Voice route" control.  Apart from that,
there's just a change to twl4030_init_chip() that might just be cleanup,
or which might be fine for A3.

Therefore, _maybe_ the only change that A3 needs is for the "Voice
route" control to be "Voice to SoC" instead of "Voice to twl4030".

I'll try that out anyway, but would appreciate your comments if you have
