[PATCH v2 4/6] extcon: arizona: Add device binding for jack detect polarity inversion

From: Charles Keepax
Date: Fri Sep 11 2015 - 08:40:10 EST


By default the driver expects the jackdet pin to be pulled low when a
jack is inserted. This patch adds a device binding that allows the user
to specify that the jackdet pin will be pulled high when a jack is
inserted.
