From: Krzysztof Kozlowski <krzk@kernel.org>
[ Upstream commit cb31334687db31c691901269d65074a7ffaecb18 ]
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.
