   4 Subject: [PATCH 059/182] spmi: pm: drop bus-level PM suspend/resume routines
   5
   6 SPMI defines the behavior of a device in the "SLEEP" state as being
   7 "user-defined or specified by the device manufacturer".  Without
   8 clearly-defined bus-level semantics for low-power states, push the
   9 responsibility of transitioning a device into/out of "SLEEP" into SPMI
  10 device drivers.
