Userspace can't easily discover how much of a sleep cycle was spent in a hardware sleep state without using kernel tracing and vendor specific sysfs or debugfs files. To make this information more discoverable, introduce 3 new sysfs files: 1) The time spent in a hw sleep state for last cycle. 2) The time spent in a hw sleep state since the kernel booted 3) The maximum time that the hardware can report for a sleep cycle. All of these files will be present only if the system supports s2idle. Reviewed-by:
