From 41fdefb351ae4880f35ce356458a231835653fdc Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Thu, 10 Dec 2020 22:25:17 +0100 Subject: [PATCH] ARM: dts: exynos: correct fuel gauge interrupt trigger level on GT-I9100 [ Upstream commit 46799802136670e00498f19898f1635fbc85f583 ] The Maxim fuel gauge datasheets describe the interrupt line as active low with a requirement of acknowledge from the CPU. The falling edge interrupt will mostly work but it's not correct.
