Subject: ARM: dts: exynos: correct PMIC interrupt trigger level on Arndale
 Octa
Git-commit: 1ac8893c4fa3d4a34915dc5cdab568a39db5086c
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.
