[PATCH 4.19 027/247] ARM: dts: exynos: correct PMIC interrupt trigger level on Artik 5

[Greg Kroah-Hartman]

From: Krzysztof Kozlowski <krzk@xxxxxxxxxx>

[ Upstream commit cb31334687db31c691901269d65074a7ffaecb18 ]

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")
