From 56a6cd3196c6617697b46c3861dfd06579ef43d2 Mon Sep 17 00:00:00 2001 From: Baolin Wang Date: Mon, 5 Nov 2018 15:39:06 +0800 Subject: dt-bindings: power: Introduce one property to present the battery internal resistance The internal resistance of a battery is not a constant in its life cycle, this varies over the age of the battery or temperature and so on. But we just want use one constant battery internal resistance to estimate the battery capacity. Thus this patch introduces one property to present the battery factory internal resistance for battery information.
