I'm wondering if this should be optional.
Even though the display needs the reset line to be driven, it doesn't have to be so by a gpio, I believe you can even get away with just using a resistor as a reset circuit.
Not terribly important, it's up to you.
It can be made optional later if needed, so I'm going to leave it as-is.
