[PATCH v4 4/6] dt-bindings: document open-drain property

Martin Kelly <martin@xxxxxxxxxxxxxxxx> · Sat, 2 Feb 2019 13:55:59 -0800

From: Martin Kelly <martin@xxxxxxxxxxxxxxxx>

We have added an optional boolean property for configuring a BMI160
interrupt pin as open-drain, as opposed to the default push-pull, so
document this.
