Qualcomm Technologies Inc's (QTI) chipsets support SoC level low power modes.
SoCs Always On Processor/Resource Power Manager produces statistics of the SoC
sleep modes involving lowering or powering down of the backbone rails - Cx and
Mx and the oscillator clock, XO.

Statistics includes SoC sleep mode type, number of times LPM entered, time of
last entry, exit, and accumulated sleep duration.

This series adds a driver to read the stats produced by remote processor and
exports using sysfs.
