Subject: [PATCH v4 3/7] arm64: dts: mediatek: add apu support for mt8365
 SoC

AI Processor Unit System (APUSYS) is a highly efficient computing unit
system which is most suitable for AI/CV algorithms. It includes one
programmable AI processor (Cadence VP6) for both AI and CV algorithms,
and an eDMA engine for data movement between external DRAM and VP6
internal memory.

For more detail, ask Mediatek for the MT8365 AIoT application processor
functional specification.
