Subject: [PATCH AUTOSEL 5.7 43/58] soc: qcom: pdr: Reorder the PD state indication ack
Date: Sat,  8 Aug 2020 19:37:09 -0400	[thread overview]
Message-ID: <20200808233724.3618168-43-sashal@kernel.org> (raw)
In-Reply-To: <20200808233724.3618168-1-sashal@kernel.org>

From: Sibi Sankar <sibis@codeaurora.org>

[ Upstream commit 72fe996f9643043c8f84e32c0610975b01aa555b ]

The Protection Domains (PD) have a mechanism to keep its resources
enabled until the PD down indication is acked. Reorder the PD state
indication ack so that clients get to release the relevant resources
before the PD goes down.
