Subject: [PATCH 4/5] ARM: dts: bcm2835: Add VCHI node to the Raspberry Pi boards.
Date:   Mon,  5 Mar 2018 12:28:05 -0800
Message-Id: <20180305202806.21219-5-eric@anholt.net>
In-Reply-To: <20180305202806.21219-1-eric@anholt.net>
References: <20180305202806.21219-1-eric@anholt.net>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The VCHI firmware communication channel operates in parallel with our
other mailbox-based channel.  This is the communication channel that
exposes the firmware's media decode/encode and ISP interfaces.
