As discussed on the ML, currently headset button reports "KEY_PAUSE
released" on press and "pressed" on release. For "pause" semantics it makes
sense but if someone thinks of that as of just another button, it'd be good
to have "pressed/released" events consistent with button press/release.
Luca Capello <luca@pca.it> suggested to change the button event to KEY_PLAY
and to invert the state to make it more consistent.
This trivial patch inverts button events for GTA03 KEY_PLUS and KEY_MINUS,
i'm not sure how undesirable that is. I can prepare an alternative that
preserves current behaviour on GTA03 per request.

global_inside_suspend only exists if CONFIG_PM is enabled.
We're actually the only ones using it outside power management,
so I guess it's okay not to try to find a more elegant solution
for upstream.

This patch filters AUX key bouncing. We store the state of
the AUX button and only change it when we notice that at
least AUX_TIMER_CONSECUTIVE_EVENTS consecutive equal GPIO
reads occur.
This should solve #2185 (AUX button makes interrupt storm)
but we still need the confirmation from someone affected by
the IRQ storm. In my test setup I could see an improvement
but I would only get 1 unwanted IRQ.
The next step is to use the same timer for more keys. For
that we could use the neo1973kbd_default_key_irq function
for the AUX key also.

Nasty temporary patch that is VERY useful, basically if you hit AUX key
during suspend time, it will force an OOPS, which due to another debug patch
forces a spew on serial console showing dmesg to date and the oops.

This file was moved in the big file move, but some OpenMoko specific
changes did not make it. This patch peels out the relevant bits and
adds them to the gpio.h file in the upstream location.
The only OpenMoko specific change is the definition of gpio_to_irq and
irq_to_gpio. These functions should really be defined in gpio_chip and
asm-generic/gpio.h; this is coming soon, but until then we'll just use
the Moko definitions that we've been using up until now.
This is not strictly correct for the GTA02 case, but it works given
the configuration that's currently in use. This can be fixed (and
should become evident) when the configuration options are cleaned up.

the KEY_PHONE is backwards. It returns up when pushed and down when

struct input_dev in include/linux/input.h used to have a union
cdev which contained the associated device struct pointer. This
got simplified out in 2.6.25, so this patch removes cdev from
our drivers that used it before.

Make sure we can't lose a jack interrupt in debounce, despite it is

Headphone jack detection is bouncy, it can trigger multiple interrupts
on insertion or removal. This patch adds a workqueue that waits out the
interrupt spew in 100ms units, and if it sees no more interrupts for 100ms
only then samples and reports the jack state. I was unable to get a bounce
after 20 or so tries after this.
