From 6ff62ca3589f88112cddf0b61d708a784b3283f4 Mon Sep 17 00:00:00 2001
From: Phil Elwell <phil@raspberrypi.org>
Date: Thu, 14 Jul 2016 10:40:20 +0100
Subject: [PATCH] config: Add driver for mcp23017 I2C GPIO expander
There is already an overlay for the mcp23017 I2C GPIO expander,
but it does nothing without the required driver module.
