Currently the panel driver sets the GPIO value to 0 to assert the reset. With the GPIO_ACTIVE_LOW flag you'd end up setting the actual level of the GPIO to high, which is going to deassert. So I think if you make the above change (which I think is the right thing to do), you'll also have to update the driver to use high-active logic. Thierry
