device attr's should be static, otherwise duplicate identifiers are

Simple example of how a gpio trigger driver would work.
Things to be added include interupt type control (high, low).

The original posting of this driver led to a discussion in
which it was commented that a better system was needed
for dealing with the many possible periodic interrupt
sources available on some SoCs. Unfortunately that is
a big task and as far as I know, no-one has taken it
on as yet. So in the meantime this driver is still
in here.
