[PATCH v7 4/6] ARM: dts: sunxi: h3/h5: Add msgbox node

From: Samuel Holland
Date: Sat Feb 22 2020 - 23:09:24 EST


The H3 and H5 SoCs contain 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.
