From 87e77e46c61a9333227ab41cdefb1875758a4f13 Mon Sep 17 00:00:00 2001 From: Dirk Behme Date: Wed, 2 Sep 2015 20:07:10 +0200 Subject: Documentation: gpio: board: describe the con_id parameter The con_id parameter has to match the GPIO description and is automatically extended by the GPIO suffix if not NULL. I had to look into the code to understand this and properly find the GPIO I've been looking for, so document this.
