From mboxrd@z Thu Jan 1 00:00:00 1970 From: david@lechnology.com (David Lechner) Date: Sun, 3 Dec 2017 15:58:15 -0600 Subject: [PATCH v2] ARM: da850: Fix LEGO EV3 battery voltage gpio Message-ID: <1512338295-10633-1-git-send-email-david@lechnology.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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.
