The MediaTek power domain driver contains a hack that assigns the device node of the power domain to the struct device of the power domain controller in order to use the devres regulator API. Now that there is a proper OF-specific regulator API, and even a devres version, replace the hack with proper code. This change is incompatible with incomplete device trees. Instead of assigning the dummy regulator in cases where the power domain requires a supply but the device tree does not provide one, the driver will just error out. This will be seen on the MT8390 EVK, which is missing supplies for the IMG_VCORE and CAM_VCORE domains. And likely all the MediaTek EVBs, which have no power domain supplies specified. This is however the correct behavior. If the power domain's supply is missing, then it should not work. Relying on other parts of the system to keep the unattached regulator enabled is likely to break in ways less easier to understand.

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.
