[ 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.
Fixes: e0cefb3f79d3 ("ARM: dts: add board dts file for Exynos3250-based Monk
board")
