arm64: dts: exynos: correct PMIC interrupt trigger level on Espresso
[ Upstream commit 1fea2eb2f5bbd3fbbe2513d2386b5f6e6db17fd7 ]
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.
