Hi Charu,

I owe you an apology.

I was wrong here.  The enable wakeup mode was supposed to be enabled by
default in the hwmod, but due to a bug[1], it was not.  This problem was
not directly related to your series.

I apologize for accusing you of not testing GPIO wakeups.  I now know
that this functionality was broken by patches independent of your
series, so I deeply regret the accusation.
