Subject: [PATCH AUTOSEL 5.6 058/606] arm64: dts: qcom: msm8996: Reduce vdd_apc voltage
Date: Mon, 8 Jun 2020 19:03:03 -0400 [thread overview]
Message-ID: <20200608231211.3363633-58-sashal@kernel.org> (raw)
In-Reply-To: <20200608231211.3363633-1-sashal@kernel.org>
From: Bjorn Andersson <bjorn.andersson@linaro.org>
commit 28810eecae08f9458a44831978e36f14ed182c80 upstream.
Some msm8996 based devices are unstable when run with VDD_APC of 1.23V,
which is listed as the maximum voltage in "Turbo" mode. Given that the
CPU cluster is not run in "Turbo" mode, reduce this to 0.98V - the
maximum voltage for nominal operation.
