Subject: [PATCH v4 06/10] ARM: dts: sunxi: a83t: Add msgbox node
Date: Mon, 19 Aug 2019 22:23:07 -0500
Message-ID: <20190820032311.6506-7-samuel@sholland.org> (raw)
In-Reply-To: <20190820032311.6506-1-samuel@sholland.org>

The A83T SoC contains a message box that can be used to send messages
and interrupts back and forth between the ARM application CPUs and the
ARISC coprocessor. Add a device tree node for it.
