0012 description: |
0013 This module is part of the sl28cpld multi-function device. For more
0014 details see ../mfd/kontron,sl28cpld.yaml.
0015
0016 There are three flavors of the GPIO controller, one full featured
0017 input/output with interrupt support (kontron,sl28cpld-gpio), one
0018 output-only (kontron,sl28-gpo) and one input-only (kontron,sl28-gpi).
0019
0020 Each controller supports 8 GPIO lines.
