Hi Paul and others,

I tried the v3.4-rc2 today, and it _seems_ gpio button wakeups don't work
anymore (ie. wakeup set up by gpio-keys driver). More specifically, the GPIO0
(power button) doesn't wakeup my board from "echo mem > /proc/power/state".

I haven't investigated much, but tracing PWER register on suspend,
while GPIO0 (power button) was set as a wakeup source gives 0x80100000, which
lacks the bit0 setting (ie. GPIO0 as a wakeup source).

I don't know it this is a recent or known issue, or if I'm have missed a change in
pxa/gpio-keys driver.

Would anyone have an idea what's happening or should I look for the issue myself ?

Cheers.
