Subject: [PATCH v3 01/13] dt-bindings: soc: qcom: aoss: Drop power-domain bindings
Date: Fri, 25 Jun 2021 00:21:55 +0530 [thread overview]
Message-ID: <1624560727-6870-2-git-send-email-sibis@codeaurora.org> (raw)
In-Reply-To: <1624560727-6870-1-git-send-email-sibis@codeaurora.org>
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 power-domain
bindings and replace them with generic qmp_send interface instead.
