Subject: [PATCH v5 6/7] ARM: dts: sun8i: v40: bananapi-m2-berry: Fix WiFi regulator definitions
Date: Tue, 23 Apr 2019 14:26:03 -0300 [thread overview]
Message-ID: <1556040365-10913-7-git-send-email-pgreco@centosproject.org> (raw)
In-Reply-To: <1556040365-10913-1-git-send-email-pgreco@centosproject.org>
Just like was done for the bananapi-m2-ultra, add the second wifi/bt
regulator and mark both as always-on.
