Subject: [PATCH 1/9] ARM: dts: exynos: correct PMIC interrupt trigger level on Artik 5
Date:   Thu, 10 Dec 2020 22:28:55 +0100
Message-Id: <20201210212903.216728-1-krzk@kernel.org>

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.
