   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.
