Subject: [PATCH] arm64: dts: clearfog-gt-8k: add wlan_disable signal hog
Date: Tue, 26 Feb 2019 08:46:11 +0200 [thread overview]
Message-ID: <936a9930fee3f285ee5538205181ca2ef1f5cbe5.1551163571.git.baruch@tkos.co.il> (raw)
From: Thomas Schreiber <tschreibe@gmail.com>
There is currently no DT binding for GPIO rfkill signals. To make
mini-PCIe attached WiFi devices work, use gpio-hog to hold the
wlan_disable signal de-asserted.
