title: Allegro DVT Video IP Codecs

maintainers:

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.
