Subject: [PATCH AUTOSEL 4.9 03/26] arm64: dts: qcom: msm8916: Pull down PDM GPIOs during sleep
Date: Fri, 21 Aug 2020 12:19:14 -0400 [thread overview]
Message-ID: <20200821161938.349246-3-sashal@kernel.org> (raw)
In-Reply-To: <20200821161938.349246-1-sashal@kernel.org>
From: Stephan Gerhold <stephan@gerhold.net>
[ Upstream commit e2ee9edc282961783d519c760bbaa20fed4dec38 ]
The original qcom kernel changed the PDM GPIOs to be pull-down
during sleep at some point. Reportedly this was done because
there was some "leakage at PDM outputs during sleep":
https://source.codeaurora.org/quic/la/kernel/msm-3.10/commit/?id=0f87e08c1cd3e6484a6f7fb3e74e37340bdcdee0
I cannot say how effective this is, but everything seems to work
fine with this change so let's apply the same to mainline just
to be sure.
