Subject: [PATCH v2 05/16] arm64: dts: mt7622: add PMIC MT6380 related nodes
Date:   Tue, 6 Feb 2018 17:52:54 +0800
Message-ID: <38270e84210144d52178def5ec7364b966a616eb.1517910489.git.sean.wang@mediatek.com>

From: Sean Wang <sean.wang@mediatek.com>

Enable pwrap and MT6380 on mt7622-rfb1 board. Also add all mt6380
regulator nodes in an alone file to allow similar boards using MT6380
able to resue the configuration.
