Currently the power supply device tree documentation is spread in .../bindings/power_supply and .../bindings/power. This unifies the files for chargers and battery fuel gauges in .../bindings/power/supply and the ones for system reset/shutdown in .../bindings/power/reset (same structure as used for the drivers itself).
