[PATCH v6 3/6] ARM: dts: sunxi: a83t: Add msgbox node

From: Samuel Holland
Date: Mon Jan 13 2020 - 00:19:16 EST


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.
