Subject: [PATCH v3 0/9] Xilinx AI engine kernel driver

AI engine is the acceleration engine provided by Xilinx. These engines
provide high compute density for vector-based algorithms, and flexible
custom compute and data movement. It has core tiles for compute and
shim tiles to interface the FPGA fabric.

You can check the AI engine architecture document for more hardware details:
https://www.xilinx.com/support/documentation/architecture-manuals/am009-versal-ai-engine.pdf

This patch series adds a Linux kernel driver to manage the Xilinx AI
engine array device and AI engine partitions (groups of AI engine tiles
dedicated to an application).

v3:
* unlock AIE dev mutex after failed to gain the partition lock in
  errors handing
* replace pointer with __u64 and enum with __u32 in ioctl

v2:
* Fix dtschema check errors
* Fix test bot warning on interrupt implementation. Removed set but
  unused  varaible.
* Fix compilation unused function warning of firmware change in case
  ZynqMP firmware is not configured
* There are other warning on ZynqMP firmware reported from testbot
  which is not introduced by this patch set.
  "[PATCH] firmware: xlnx-zynqmp: fix compilation warning" is submitted
  for those fixes.
