Subject: [PATCH v7 5/6] arm64: dts: allwinner: a64: Add msgbox node
Date: Sat, 22 Feb 2020 22:08:52 -0600 [thread overview]
Message-ID: <20200223040853.2658-6-samuel@sholland.org> (raw)
In-Reply-To: <20200223040853.2658-1-samuel@sholland.org>
The A64 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.
