Subject: ARM: dts: exynos: correct fuel gauge interrupt trigger level on Midas
 family
Git-commit: 8a45f33bd36efbb624198cfa9fdf1f66fd1c3d26
Patch-mainline: v5.13-rc1
References: git-fixes

The Maxim fuel gauge 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: e8614292cd41 ("ARM: dts: Add Maxim 77693 fuel gauge node for exynos4412-trats2")
