Hi Mika,

BTW, I failed to compile the kernel 4.4 with the patch.

The patch uses gpiochip_line_is_irq() function which has been
introduced since 4.6-rc1, so we need to cherry pick this commit, too.
   6cee382 gpio/pinctrl: sunxi: stop poking around in private vars

But the above commit uses gpiodev data member in struct gpio_chip
which is introduced from this commit, and it's a big commit that can't
be cherry-picked clearly.
   ff2b135 gpio: make the gpiochip a real device

Will you provide other patch that can apply on top of old stable kernels?

AceLan Kao.
