Are you *sure* they are grounded and not supplied from the LDOs?
That's what I have on schematics (attached), if I got it right.
You'll notice that they've got decoupling caps on rather than being grounded - there's an internal connection to the LDO output so if the LDOs are in use that's all that's required, while if the LDOs are not in use for some reason then an external supply is connected there.
Yes, indeed, not grounded. I'll rephrase the commit. I also found few other differences needed: 1. AVDD2 should be always required, 2. LDO2VDD exists on WM8994.
