 12description: |
 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.
