Subject: [PATCH 5.4 022/340] ARM: dts: exynos: correct PMIC interrupt trigger level on Odroid XU3 family

From: Krzysztof Kozlowski <krzk@...nel.org>

[ Upstream commit 3e7d9a583a24f7582c6bc29a0d4d624feedbc2f9 ]

The Samsung PMIC datasheets describe the interrupt line as active low
with a requirement of acknowledge from the CPU.  The falling edge
interrupt will mostly work but it's not correct.
