0012 description: |
0013 The Freescale PORT/GPIO modules are two adjacent modules providing GPIO
0014 functionality. Each pair serves 32 GPIOs. The VF610 has 5 instances of
0015 each, and each PORT module has its own interrupt.
0016
0017 Note: Each GPIO port should have an alias correctly numbered in "aliases"
0018 node.
