title: Allegro DVT Video IP Codecs Device Tree Bindings

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