There is currently the MX8MM GPU domain, which is in fact a composite domain for both GPU2D and GPU3D. To correctly configure this domain, it is necessary to control both GPC_PGC_nCTRL(GPU_2D) and GPC_PGC_nCTRL(GPU_3D) at the same time. This is currently not possible. Turn the domain->pgc from value into bitfield and use for_each_set_bit() to iterate over all bits set in domain->pgc when configuring GPC_PGC_nCTRL register array. This way it is possible to configure all GPC_PGC_nCTRL registers required in a particular domain. This is a preparatory patch, no functional change.

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.
