i will add this

I don't think that will work with the current driver, because the GPIO
subsystem will automatically invert the value for you. 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.
