Help text

This driver provides a tiny alternative to the ACPI Button driver. The tiny power button driver only handles the power button. Rather than notifying userspace via the input layer or a netlink event, this driver directly signals the init process to shut down.

This driver is particularly suitable for cloud and VM environments, which use a simulated power button to initiate a controlled poweroff, but which may not want to run a separate userspace daemon to process input events.
