The MediaTek AI Processing Unit (APU) is a proprietary hardware
in the SoC to support AI functions.
The patches support the MT8192 APU runs on internal microprocessor.
Software packages contins mailbox, iommu, APU remote processor,
power control, middleware and debug looger.

This series is based on drivers implemented in
MT8192 apu power domain[1], apu SMC[2] and IOMMU[2] patches.
