From: David Daney <david.daney-YGCgFSpz5w/QT0dZR+AlfA@public.gmane.org>

There are two patches needed to add OCTEON GPIO support:

1) Select ARCH_REQUIRE_GPIOLIB.  This allows standard I2C GPIO
expanders to function, as well as being a prerequisite for the driver
for the on-chip pins.

2) The on-chip pin driver.

I'm not sure the best way to merge these, they are part MIPS and part
GPIO.  Via either maintainer is fine by me.

Thanks,

  MIPS: OCTEON: Select ARCH_REQUIRE_GPIOLIB
  gpio/MIPS/OCTEON: Add a driver for OCTEON's on-chip GPIO pins.
