[ Upstream commit 437ae60947716bb479e2f32466f49445c0509b1e ]
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: faaf348ef468 ("ARM: dts: Add board dts file for exynos3250-rinato")
