[PATCH 0/4] misc: add ArmChina Zhouyi NPU driver

[Dejia Shang]

Hi,

These 4 patches add supports to the ArmChina Zhouyi NPU IPs.

The Zhouyi NPUs (and software for it) are designed by Arm Technology (China) Co. Ltd.,
i.e. short for ArmChina, for edge AI computing devices in markets like smart home, auto,
IoT, mobile, etc. The brand name "Zhouyi" comes from a Chinese traditional classic about
changes and predictions. Currently two versions of Zhouyi IP (Z1 and Z2) are released,
and they are integrated into SoC chips Allwinner R329 and Siengine SE1000, respectively.

This driver supports the control of Zhouyi Z1 and Z2 NPUs. By using the user mode driver
APIs, application program can schedule AI inference tasks on Zhouyi NPUs efficiently. The
user mode part of this driver is opensourced now and anyone can fetch it from github:
https://github.com/dejsha01/armchina-zhouyi.

We found that a few days ago someone submitted a legacy version of Zhouyi NPU driver:
https://lore.kernel.org/lkml/20211126021904.32325-1-caihuoqing@baidu.com/#t.
We think that the current version in these 4 patches is better for upstreaming because
it contains bug-fixes and code optimizations compared with the legacy version,
and the corresponding user mode driver for this kernel driver is opensourced.

I would appricate any feedback, question or review :)

Thanks,
Dejia
