Subject: [PATCH v6 01/13] dt-bindings: soc: qcom: aoss: Drop the load state power-domain
Date:   Mon,  6 Sep 2021 13:53:45 +0530
Message-Id: <1630916637-4278-2-git-send-email-sibis@codeaurora.org>
In-Reply-To: <1630916637-4278-1-git-send-email-sibis@codeaurora.org>
References: <1630916637-4278-1-git-send-email-sibis@codeaurora.org>
Precedence: bulk

The power-domains exposed by AOSS QMP node are used to notify the Always
on Subsystem (AOSS) that a particular co-processor is up/down. These
co-processors enter low-power modes independent to that of the application
processor and their states are expected to remain unaltered across system
suspend/resume cycles. To achieve this behavior let's drop the load
power-domain and replace them with generic qmp_send interface instead.
