Subject: [PATCH 4/5] dt-bindings: power: sc27xx: Add a new property to describe the real resistance of coulomb counter chip
Date: Mon, 28 Oct 2019 15:19:00 +0800	[thread overview]
Message-ID: <00202f739348258555dcc40982c330542ac61863.1572245011.git.baolin.wang@linaro.org> (raw)

In-Reply-To: <cover.1572245011.git.baolin.wang@linaro.org>

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.
