From e8614292cd41971b54e60188d4e99abdc8695073 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Wed, 4 Feb 2015 07:43:44 +0900 Subject: [PATCH] ARM: dts: Add Maxim 77693 fuel gauge node for exynos4412-trats2 Add node for fuel gauge present in Maxim 77693 PMIC. This allows control over battery charging state on Trats2 board. The fuel gauge is compatible with max17042 battery driver (Maxim 17042/17047/17050). Although datasheet rev 2.2 for MAX77693 describes fuel gauge as Maxim 17042-like, the chip on Trats2 board identifies itself as Maxim 17047-like.
