description: |
  This module is part of the sl28cpld multi-function device. For more
  details see ../mfd/kontron,sl28cpld.yaml.
 
  There are three flavors of the GPIO controller, one full featured
  input/output with interrupt support (kontron,sl28cpld-gpio), one
  output-only (kontron,sl28-gpo) and one input-only (kontron,sl28-gpi).
 
  Each controller supports 8 GPIO lines.
