Subject: [PATCH v4 1/4] dt-bindings: Introduce SoC sleep stats bindings
Date: Mon,  9 Mar 2020 16:44:14 +0530	[thread overview]
Message-ID: <1583752457-21159-2-git-send-email-mkshah@codeaurora.org> (raw)
In-Reply-To: <1583752457-21159-1-git-send-email-mkshah@codeaurora.org>

From: Mahesh Sivasubramanian <msivasub@codeaurora.org>

Add device binding documentation for Qualcomm Technologies, Inc. (QTI)
SoC sleep stats driver. The driver is used for displaying SoC sleep
statistic maintained by Always On Processor or Resource Power Manager.

+description:
+  Always On Processor/Resource Power Manager maintains statistics of the SoC
+  sleep modes involving powering down of the rails and oscillator clock.
+
+  Statistics includes SoC sleep mode type, number of times low power mode were
+  entered, time of last entry, time of last exit and accumulated sleep duration.

+  compatible:
+    enum:
+      - qcom,rpmh-sleep-stats

+  - compatible
+  - reg
