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.
