Subject: [PATCH 5.10 124/530] ARM: dts: s5pv210: correct fuel gauge interrupt trigger level on Fascinate family

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

[ Upstream commit 214e6ec8c9f5a3353d3282b3ff475d3ee86cc21a ]

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.
