4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: David Lechner <david@xxxxxxxxxxxxxx>
commit c5a88cd2e1c508868922bafa0a5c3365986b98e5 upstream.
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.
Also, there was a typo that prevented pinmuxing from working correctly.
