From 1fae580ed43234c5f5be7ee9ce18030a670b5da1 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Mon, 15 Mar 2021 06:37:16 +0000 Subject: [PATCH] ARM: dts: exynos: correct PMIC interrupt trigger level on Artik 5 stable inclusion from stable-5.10.20 commit 83830e692f28f02b75015c924d00dfe30fa0558a bugzilla: 50608 -------------------------------- [ Upstream commit cb31334687db31c691901269d65074a7ffaecb18 ] 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.
