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.

System Power Management Interface (SPMI) is a specification
developed by the MIPI (Mobile Industry Process Interface) Alliance
optimized for the real time control of Power Management ICs (PMIC).
SPMI is a two-wire serial interface that supports up to 4 master
devices and up to 16 logical slaves.
The framework supports message APIs, multiple busses (1 controller
per bus) and multiple clients/slave devices per controller.
