title: GPIO driver for the sl28cpld board management controller
maintainers:

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.
