Subject: [PATCH 2/2] ARM: dts: qcom: msm8974-lge-nexus5: Add fuel gauge
Date: Thu, 26 Nov 2020 16:11:44 +0200 [thread overview]
Message-ID: <20201126141144.1763779-2-iskren.chernev@gmail.com> (raw)
In-Reply-To: <20201126141144.1763779-1-iskren.chernev@gmail.com>
The LG Nexus 5 uses a maxim17048 fuelgauge. The maxim,rcomp value is
taken from downstream dt. Temperature-based compensation is not yet
supported in the mainline driver, but the readings seem fine nevertheless.
