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

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.

Fixes: b004a34bd0ff ("ARM: dts: exynos: Add exynos3250-artik5 dtsi file for ARTIK5 module")
