I have a board with VR4181A. I would like to read/write
the General I/O port but I can't find anything how to do it.

I could wrote a small driver to setup and handle an interrupt
on GUINT0 using vr41xx_set_irq_trigger (a simple switch is
connected to PIN0)
But I need to set/clear pins to be able to connect an EEPROM
to GPIO and some other stuff.

I can't find functions to do this simple like set_gio(pin, state).

Can someone help?

The board is not known by anyone, it's made in Japan
