Subject: [PATCH v2 06/10] ARM: dts: sunxi: a80: Add msgbox node
Date:   Thu, 28 Feb 2019 23:29:43 -0600
Message-Id: <20190301052947.32032-7-samuel@sholland.org>

Precedence: bulk

The A80 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.
