Subject: [PATCH 2/9] ARM: dts: exynos: correct PMIC interrupt trigger level on Monk
Date: Thu, 10 Dec 2020 22:28:56 +0100 [thread overview]
Message-ID: <20201210212903.216728-2-krzk@kernel.org> (raw)
In-Reply-To: <20201210212903.216728-1-krzk@kernel.org>
The Samsung PMIC datasheets describe the interrupt line as active low
with a requirement of acknowledge from the CPU. Without specifying the
interrupt type in Devicetree, kernel might apply some fixed
configuration, not necessarily working for this hardware.
Fixes: e0cefb3f79d3 ("ARM: dts: add board dts file for Exynos3250-based Monk board")
Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>
