Subject: [PATCH 0/2] Introduce SoC sleep stats driver
Date: Thu,  8 Aug 2019 11:42:26 +0530	[thread overview]
Message-ID: <20190808061228.16573-1-mkshah@codeaurora.org> (raw)

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.
