Controlling output pin

Hi all,

I once found a small example somewhere which used an output pin of the
P1 connector of the EP405 board. It just outputted a square wave.
Now, I don't find it anymore, and I like to get it back, because it's
the perfect start for a kernel module I need to write.
Perhaps anybody else have another example on how to use an output
directly.

The target of my module:
* generate 2 PWM signals on 2 output pins.
* do this all in real time (with RTAI).

I rather start from an example, than start from scratch (because I never
dealt with direct pin control before).

So, if anybody van help me out with this, it's much appreciated.
