| Subject: ARM: dts: exynos: correct fuel gauge interrupt trigger level on P4 |
| Note family |
| |
| From: Krzysztof Kozlowski <krzk@kernel.org> |
| |
| [ Upstream commit c731a16e2cf424a462c7d42c33d6acd613576508 ] |
| |
| 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. |
