Subject: ARM: dts: exynos: correct PMIC interrupt trigger level on Odroid XU3
 family
Git-commit: 3e7d9a583a24f7582c6bc29a0d4d624feedbc2f9
Patch-mainline: v5.12-rc1
References: git-fixes

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")
