The Allwinner T527 SoC has an NPU built in. Based on identifiers found in the BSP, it is a Vivante IP block. After enabling it, the etnaviv driver reports it as a GC9000 revision 9003. The standard bindings are used as everything matches directly. There is no option for DVFS at the moment. That might require some more work, perhaps on the efuse side to map speed bins. It is unclear whether the NPU block is fused out at the hardware level or the BSP limits use of the NPU through software, as the author only has boards with the T527.

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 reStructuredText 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.
