   1 GPIO driver for MAX77620 Power management IC from Maxim Semiconductor.
   2
   3 Device has 8 GPIO pins which can be configured as GPIO as well as the
   4 special IO functions.
   5
   6 Required properties:
   7 -------------------
   8 - gpio-controller :     Marks the device node as a gpio controller.
   9 - #gpio-cells :         Should be two.  The first cell is the pin number and
  10                         the second cell is used to specify the gpio polarity:
  11                                 0 = active high
  12                                 1 = active low
