From: Krzysztof Kozlowski Date: Thu, 10 Dec 2020 21:28:56 +0000 (+0100) Subject: ARM: dts: exynos: correct PMIC interrupt trigger level on Monk X-Git-Tag: v4.14.223~162 X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=61b783b014a8fb669cf587c83fa8500bd3fd6358;p=users%2Fdwmw2%2Flinux.git 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.
