// Switch events describe stateful binary switches. For example,
// the SwLid code is used to denote when a laptop lid is closed.
//
// Upon binding to a device or resuming from suspend, a driver must report
// the current switch state. This ensures that the device, kernel, and userspace
// state is in sync.
//
// Upon resume, if the switch state is the same as before suspend, then the input
// subsystem will filter out the duplicate switch state reports. The driver does
// not need to keep the state of the switch at any time.
