Please don't do that, it really is no gpiolib implementation.

In the archives you can find patches I already submitted switching
the U300 GPIO over to use gpiolib.

However it fell to the ground due to the shortage of a mechanism
in gpiolib to configure pin bias. I could try to hack around it but
it would still be a hack :-(

I sent several patches trying to adress that issue, none have been
accepted.

So instead I venture into inventing the pin control subsystem which
is intended to handle complex controllers like these. It is at
version 7 right now.

Thanks,
