From 45dfa741df8607ee4a45455c194ce654badb2478 Mon Sep 17 00:00:00 2001 From: Iskren Chernev Date: Thu, 26 Nov 2020 16:11:44 +0200 Subject: [PATCH] ARM: dts: qcom: msm8974-lge-nexus5: Add fuel gauge MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit 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.
