| Subject: ARM: dts: exynos: correct fuel gauge interrupt trigger level on |
| GT-I9100 |
| |
| From: Krzysztof Kozlowski <krzk@kernel.org> |
| |
| [ Upstream commit 46799802136670e00498f19898f1635fbc85f583 ] |
| |
| 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. |
