- * Power and battery LED control for Nami and its variants
- *
- * This is an event-driven LED control library. It does not use tasks or
- * periodical hooks (HOOK_TICK, HOOK_SECOND), thus, it's more resource
- * efficient.
- *
- * The library defines LED states and assigns an LED behavior to each state.
- * The state space consists of tuple of (charge state, power state).
- * In each LED state, a color and a pulse interval can be defined.
- *
- * Charging states are queried each time there is a state transition, thus, not
- * stored. We hook power state transitions (e.g. s0->s3) and save the
- * destination states (e.g. s3) in power_state.
- *
- * When system is suspending and AC is unplugged, there will be race condition
- * between a power state hook and a charge state hook but whichever is called
- * first or last the result will be the same.
- *
- * Currently, it supports two LEDs, called 'battery LED' and 'power LED'.
- * It assumes the battery LED is connected to a PWM pin and the power LED is
- * connected to a regular GPIO pin.
