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.
