In order to support the complex power sequencing required by the TH1520 GPU, the AON power domain driver must be responsible for initiating the corresponding sequencer driver. This functionality is specific to platforms where the GPU power sequencing hardware is controlled by the AON block. Extend the AON power domain driver to check for the presence of the "gpu-clkgen" reset in its own device tree node. If the property is found, create and register a new auxiliary device. This device acts as a proxy that allows the dedicated `pwrseq-thead-gpu` auxiliary driver to bind and take control of the sequencing logic.

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.
