Subject: [PATCH v4 4/7] ARM: dts: sun8i: v40: bananapi-m2-berry: Fix WiFi regulator definitions
Date:   Thu, 18 Apr 2019 12:11:19 -0300

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Just like was done for the bananapi-m2-ultra, add the second wifi/bt
regulator and mark both as always-on.
