Subject: [PATCH v2 2/2] soc: qcom: aoss: Use both GENPD_FLAG_NO_SUSPEND/RESUME flags
Date: Sat, 22 Aug 2020 02:19:21 +0530 [thread overview]
Message-ID: <20200821204921.32536-2-sibis@codeaurora.org> (raw)
In-Reply-To: <20200821204921.32536-1-sibis@codeaurora.org>
All the power domains exposed as part of the AOSS QMP driver require to
stay unaltered during suspend/resume. They are powered on when the remote
processors boots up and powered off on remote processor crash/shutdown.
Mark the power domains with GENPD_FLAG_NO_SUSPEND and GENPD_FLAG_NO_RESUME
to model this behavior.
