The NPU is based on the Vivante GC8000 and its power-domain is controlled my pgc_mlmix. Since the power-domain uses some of these clocks, setup the clock parent and rates inside the power-domain, and add the NPU node. The data sheet states the CLK_ML_AHB should be 300MHz for nominal, but 800MHz clock will divide down to 266 instead. Boards which operate in over-drive mode should update the clocks on their boards accordingly. When the driver loads, the NPU numerates as: etnaviv-gpu 38500000.npu: model: GC8000, revision: 8002 Signed-off-by: Adam Ford <aford173@gmail.com> Reviewed-by: Alexander Stein <alexander.stein@ew.tq-group.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
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.
