Subject: [PATCH v8 1/5] dt-bindings: Introduce SoC sleep stats bindings
Date: Fri, 21 May 2021 16:56:07 +0530	[thread overview]
Message-ID: <1621596371-26482-2-git-send-email-mkshah@codeaurora.org> (raw)
In-Reply-To: <1621596371-26482-1-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.
