12description: |-
13  Allegro DVT video IP codecs present in the Xilinx ZynqMP SoC. The IP core may
14  either be a H.264/H.265 encoder or H.264/H.265 decoder ip core.
15
16  Each actual codec engine is controlled by a microcontroller (MCU). Host
17  software uses a provided mailbox interface to communicate with the MCU. The
18  MCUs share an interrupt.
