Subject: [PATCH v2 08/10] ARM: dts: sunxi: h3/h5: Add msgbox node
Date: Thu, 28 Feb 2019 23:29:45 -0600 [thread overview]
Message-ID: <20190301052947.32032-9-samuel@sholland.org> (raw)
In-Reply-To: <20190301052947.32032-1-samuel@sholland.org>
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.
