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.
