Koen,
Apologies on a late response.

earlier in this function, we do:
	gpio_request(gpio + 1, "EHCI_nOC");
  	gpio_direction_input(gpio + 1);
here we do
gpio_request(gpio + 1, "nDVI_PWR_EN");
gpio_direction_output(gpio + 1, 0);

I am confused. is gpio+1 input or output line? and what level should it be on?
