From a HW point of view you can find documentation for pin-muxing and GPIO
control in the TRM documentation (spruf98b.pdf).

You mainly need to look at the following two chapters:
7. System Control Module - (In order to gain knowledge about pin-muxing)
24. General-Purpose I/O (PGIO) Interface - (In order to gain knowledge about
the GPIO functionality)

AFAIK Linux already have a framework for GPIO handling, but I don't know it
in details - yet. In case your question was more related to this, than to
the actual HW-stuff I will let it be up to somebody else to answer...

Best Regards - Good Luck
