Subject: [PATCH v3 05/15] ARM: dts: sunxi: a80: Add msgbox node
Date: Fri, 1 Mar 2019 22:29:41 -0600 [thread overview]
Message-ID: <20190302042951.53671-6-samuel@sholland.org> (raw)
In-Reply-To: <20190302042951.53671-1-samuel@sholland.org>
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.
