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.
