Pressing the PEK (power enable key) will shutdown the board. Some events are reported to devd via system "PMU" and subsystem "Battery", "AC" and "USB" such as connected/disconnected. Some sensors values (power source voltage/current) are reported via sysctl (dev.axp209_pmu.X.) It also expose a gpioc node usable in kernel and userland. Only 3 of the 4 GPIO are exposed (The GPIO3 is different and mostly unused on boards). Most popular boards uses GPIO1 as a sense pin for OTG power. Add a dtsi file that adds gpio-controller capability to the device as upstream doesn't defined it and include it in our custom DTS.
