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