Hi Wei,

thanks for your patch!

This doesn't apply for my "devel" branch, can you rebase
on this:
https://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio.git/log/?h=devel

We have moved some ACPI headers around recently.

Makes sense.

I doubt this is a regression since I haven't seen anyone use this
gpiochip with ACPI before.

Please rename the patch "gpio: pl061: Add ACPI support" unless
you can convince me it worked without changes before.

Please include some ACPI people on review of this. From

I would also include Andy Shevchenko and Mika Westerberg for
the GPIO aspects.

Thanks!
