Extend the existing Tegra186 GPIO controller device tree bindings with support for the GPIO controller found on Tegra264. The number of pins is slightly different, but the programming model remains the same. Add a new header, include/dt-bindings/gpio/nvidia,tegra264-gpio.h, that defines port IDs as well as the TEGRA264_MAIN_GPIO() helper, both of which are used in conjunction to create a unique specifier for each pin. On Tegra, GPIO wake events are latched and routed via the PMC. Document the standard DT property, wakeup-parent, which is a phandle to the PMC interrupt controller that provides the parent wake interrupt domain for the GPIO controller. If the property is absent the driver falls back to a compatible-based lookup.
