The HiSilicon IP08 and HiSilicon IP09 are DMA iEPs, they have the same pci device id but different pci revision. Unfortunately, they have different register layouts, so the origin driver cannot run on HiSilicon IP09 correctly. This patch enables the driver to adapt to HiSilicon IP09. HiSilicon IP09 offers 4 channels, each channel has a send queue, a complete queue and an interrupt to help to do tasks. This DMA engine can do memory copy between memory blocks.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
