  12 description: |
  13   The Freescale PORT/GPIO modules are two adjacent modules providing GPIO
  14   functionality. Each pair serves 32 GPIOs. The VF610 has 5 instances of
  15   each, and each PORT module has its own interrupt.
  16
  17   Note: Each GPIO port should have an alias correctly numbered in "aliases"
  18   node.
