| 12 | description: | |
| 13 | This module is part of the sl28cpld multi-function device. For more |
| 14 | details see ../mfd/kontron,sl28cpld.yaml. |
| 15 | |
| 16 | There are three flavors of the GPIO controller, one full featured |
| 17 | input/output with interrupt support (kontron,sl28cpld-gpio), one |
| 18 | output-only (kontron,sl28-gpo) and one input-only (kontron,sl28-gpi). |
| 19 | |
| 20 | Each controller supports 8 GPIO lines. |
