Subject[PATCH 5.10 118/530] ARM: dts: exynos: correct fuel gauge interrupt trigger level on Midas family
Date
From: Krzysztof Kozlowski <krzk@kernel.org>

[ Upstream commit 8a45f33bd36efbb624198cfa9fdf1f66fd1c3d26 ]

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")
