Subject: [PATCH 2/2] soc: qcom: aoss: Use GENPD_FLAG_SUSPEND_ON flag
Date: Wed, 12 Aug 2020 00:32:52 +0530	[thread overview]
Message-ID: <20200811190252.10559-2-sibis@codeaurora.org> (raw)
In-Reply-To: <20200811190252.10559-1-sibis@codeaurora.org>

All the power domains exposed as part of AOSS QMP driver require to stay
powered on for suspend. 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_SUSPEND_ON to model this behavior.
