Subject: [PATCH v6 3/6] ARM: dts: sunxi: a83t: Add msgbox node
Date: Sun, 12 Jan 2020 23:18:49 -0600 [thread overview]
Message-ID: <20200113051852.15996-4-samuel@sholland.org> (raw)
In-Reply-To: <20200113051852.15996-1-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.
