| Subject: ARM: dts: exynos: correct fuel gauge interrupt trigger level on Midas |
| family |
| |
| 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") |
