I can't see any references to GLOBAL_EN outside this function, why might it not be set?
This check prevents an incorrect 'PDN Failed' message if DAPM initializes and turns the widget off at boot (with no prior power-up).
In what way does it prevent this message and why is this a good approach to the issue?
There is a better approach that I will include in v4. The chip has a bit field that indicates if GLOBAL_EN has been asserted. The 'PDN Failed' message can be skipped if this bit is not set.
