Subject: ARM: dts: exynos: correct PMIC interrupt trigger level on Spring
Git-commit: 77e6a5467cb8657cf8b5e610a30a4c502085e4f9
Patch-mainline: v5.12-rc1
References: git-fixes

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.
