This is a note to let you know that I've just added the patch titled ARM: dts: exynos: correct PMIC interrupt trigger level on Monk to the 4.19-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: arm-dts-exynos-correct-pmic-interrupt-trigger-level-.patch and it can be found in the queue-4.19 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit a689a566d325caa5eba3764bf65390dfa3f0a9e0 Author: Krzysztof Kozlowski <krzk@xxxxxxxxxx> Date: Thu Dec 10 22:28:56 2020 +0100 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.
