Using the regulator_bulk APIs, the handling of power supplies becomes much simpler. There is no need anymore to check if regulators have been acquired or not, the bulk APIs will do all the work for us. We can also drop the various handles to the individual power supplies in the driver runtime data and instead simply treat them all as one thing. Error cleanup also becomes much simpler. Converting to the regulator_bulk APIs also makes it easier to add support for those SoCs that have additional power supplies for the PHY. Google Tensor gs101 is one example of such a SoC. Otherwise we'd have to add all additional supplies individually via individual calls to regulator_get() and enable/disable handle them all individually, including complicated error handling. That doesn't scale and clutters the code. Just update the code to use the regulator_bulk APIs.

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.
