[PATCH 4/5] dt-bindings: power: sc27xx: Add a new property to describe the real resistance of coulomb counter chip
From: Baolin Wang
Date: Mon Oct 28 2019 - 03:20:11 EST
Add a new property to describe the real resistance of coulomb counter chip,
which is used to calibrate the accuracy of the coulomb counter chip.
