Mika can you help out looking at this patch. Tell me if you need a copy
of the whole patch, I'm not smart with ACPI.

This patch modifies the DesignWare GPIO controller driver to
support the GPIO-signaled ACPI Events. This is used for power
button function on ARM server.

To make it work, the _AEI and _EVT object must be defined in
the corresponding GPIO driver's dsdt table in UEFI. At the same
time, ACPI daemon component is also necessary.

You should only need <linux/driver.h>

Here, I don't understand well. I used driver.h instead acpi.h and
gpio.h, but it came to compile failed.

Argh sorry.
<linux/gpio/driver.h>
