+What: /sys/devices/.../power/state
+ dev->power.power_state
+ dpm_runtime_{suspend,resume)()
+When: July 2007
+Why: Broken design for runtime control over driver power states, confusing
+ driver-internal runtime power management with: mechanisms to support
+ system-wide sleep state transitions; event codes that distinguish
+ different phases of swsusp "sleep" transitions; and userspace policy
+ inputs. This framework was never widely used, and most attempts to
+ use it were broken. Drivers should instead be exposing domain-specific
+ interfaces either to kernel or to userspace.
