Subject: [PATCH 03/18] ARM: dts: exynos: correct fuel gauge interrupt trigger level on Midas family
Date: Thu, 10 Dec 2020 22:25:19 +0100
Message-ID: <20201210212534.216197-3-krzk@kernel.org> (raw)
In-Reply-To: <20201210212534.216197-1-krzk@kernel.org>

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")
Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>
