From ff11ece44c2db61dda845cca48ce2bd7580b16cf Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Thu, 10 Dec 2020 22:29:00 +0100 Subject: [PATCH] ARM: dts: exynos: correct PMIC interrupt trigger level on Odroid XU3 family [ Upstream commit 3e7d9a583a24f7582c6bc29a0d4d624feedbc2f9 ] The Samsung PMIC 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.
