From f716c60cb017200284c56d512952da3be02dfc5c Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Thu, 10 Dec 2020 22:28:56 +0100 Subject: [PATCH] ARM: dts: exynos: correct PMIC interrupt trigger level on Monk [ Upstream commit 8528cda2b7c667e9cd173aef1a677c71b7d5a096 ] The Samsung PMIC datasheets describe the interrupt line as active low with a requirement of acknowledge from the CPU. Without specifying the interrupt type in Devicetree, kernel might apply some fixed configuration, not necessarily working for this hardware.
