In-Reply-To: <20180307185716.17449-1-eric@anholt.net> References: <20180307185716.17449-1-eric@anholt.net> Message-ID: <20180307185716.17449-4-eric@anholt.net> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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.
