title: Freescale VF610 PORT/GPIO module
maintainers:
- Stefan Agner <stefan@agner.ch>
description: |
The Freescale PORT/GPIO modules are two adjacent modules providing GPIO
functionality. Each pair serves 32 GPIOs. The VF610 has 5 instances of
each, and each PORT module has its own interrupt.
Note: Each GPIO port should have an alias correctly numbered in "aliases"
node.
