7 title: NVIDIA Tegra GPIO Controller (Tegra186 and later)
14   Tegra186 contains two GPIO controllers; a main controller and an "AON"
20   The Tegra186 GPIO controller allows software to set the IO direction of,
21   and read/write the value of, numerous GPIO signals. Routing of GPIO signals

44     alphabetical port name and an integer GPIO name within the port. For
