Subject: [PATCH v5 02/13] dt-bindings: remoteproc: qcom: pas: Add QMP property
Date: Thu, 19 Aug 2021 08:32:05 +0530 [thread overview]
Message-ID: <1629342136-3667-3-git-send-email-sibis@codeaurora.org> (raw)
In-Reply-To: <1629342136-3667-1-git-send-email-sibis@codeaurora.org>
The load state power-domain, used by the co-processors to notify the
Always on Subsystem (AOSS) that a particular co-processor is up/down,
suffers from the side-effect of changing states during suspend/resume.
However the 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 state power-domain and replace them with the qmp
property for all SoCs supporting low power mode signalling.
