Subject: [PATCH 5.11 228/601] ARM: dts: qcom: msm8974-lge-nexus5: correct fuel gauge interrupt trigger level

From: Krzysztof Kozlowski <krzk@...nel.org>

[ Upstream commit 9d816b423dab5b59beec5e39b97428feac599ba7 ]

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.
