Subject: [PATCH 6/9] ARM: dts: exynos: correct PMIC interrupt trigger level on Odroid XU3 family

From: Krzysztof Kozlowski <[email-masked]>
Date: Thu, 10 Dec 2020 22:29:00 +0100

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.

Fixes: aac4e0615341 ("ARM: dts: odroidxu3: Enable wake alarm of S2MPS11 RTC")
