Subject: [PATCH] ARM: da850: Fix LEGO EV3 battery voltage gpio
Date: Sun,  3 Dec 2017 13:29:33 -0600	[thread overview]
Message-ID: <1512329373-17321-1-git-send-email-david@lechnology.com> (raw)

This fixes the battery voltage monitoring gpio-hog settings.

When the gpio is low, it turns off the battery voltage to the ADC chip.
However, this needs to be on all of the time so that we can monitor
battery voltage.
