Subject: [PATCH] ARM: dts: sun8i-h2-plus-bananapi-m2-zero: add gpio-poweroff to DT
Date:   Mon, 23 Nov 2020 17:10:41 +0100
Message-Id: <20201123161041.2304766-1-michael@fossekall.de>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Add gpio-poweroff node to allow the board to power itself off after
shutdown by disabling the SYSTEM and CPUX regulators (U5 resp. U6).
The RST button can be used to restart the board.
