From: Greg Kroah-Hartman
Date: Tue May 23 2017 - 17:08:29 EST


3.18-stable review patch. If anyone has any objections, please let me know.

------------------

From: Ludovic Desroches <ludovic.desroches@xxxxxxxxxxxxx>

commit 9cdd31e5913c1f86dce7e201b086155b3f24896b upstream.

The voltage reference for the ADC is not 3V but 3.3V since it is connected to
VDDANA.
