OK, good - the fact that the connection wasn't being made with the PMIC
was my main point here.

Did you read writed mail about consumer supply of WM8994 by MyungJoo Ham?

I saw it, yes.

He is in charge of PMIC and Power Management on Aquila board.

MyungJoo Ham is wrote : 
This aquila_buck3_data.constraints would be better have ".always_on =
1" entry as this buck3 is required to be turned on at all times in
Aquila boards (even when the system is in suspend-to-mem state). This
is required especially when there are many devices physically attached
to Buck3 and some of they did not "register" as consumers to Buck3.
Buck3 might be turned off by those who are registered while
"unregistered" are still active.

Can you tell me your opinion about the review by MyungJoo Ham?
I will respect your response.

I think his comments are sensible.  The constraints should always try to
reflect the actual constraints of the system as closely as possible.
