Subject: [PATCH v2 4/6] ARM: dts: bcm2835: Add VCHIQ node to the Raspberry Pi boards.
Date: Wed, 7 Mar 2018 10:57:14 -0800 [thread overview]
Message-ID: <20180307185716.17449-4-eric@anholt.net> (raw)
In-Reply-To: <20180307185716.17449-1-eric@anholt.net>
The VCHIQ 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.
