Subject: [PATCH v2] ARM: dts: sun8i-h2-plus-bananapi-m2-zero: add poweroff node to DT
Date: Tue, 24 Nov 2020 14:36:33 +0100 [thread overview]
Message-ID: <20201124133633.672259-1-michael@fossekall.de> (raw)
In-Reply-To: <20201124131933.2l2go6z6ltar5fpa@gilmour>
Add 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.
