The GPIO driver patch was proposed on lkml a few days ago and although I
am not aware of any "GENERIC" methods it uses it does not compile
without GENERIC_GPIO being defined (errors in of_gpio.h etc). You can
review the patch at https://lkml.org/lkml/2013/4/10/385.

We'd be happy to accept any guidance on how to remove GENERIC_GPIO.
Also, I'm not sure the custom interface to the pin controller is a great
solution and suggestions are welcome. The goal is to remove redundancy
between the drivers in the definition of pin groups.

Regards,
  Christian
