Subject: [PATCH v4 05/10] ARM: dts: sunxi: a80: Add msgbox node

From: Samuel Holland <[email-masked]>
Date: Mon, 19 Aug 2019 22:23:06 -0500

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.
