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.

Newer platforms vote for necessary power domains through the power domain subsystem. For historical reasons older platforms like MSM8916 or MSM8974 still control these as regulators. Managing them as power domains is preferred since that allows us to vote for corners instead of raw voltages. Make it possible for MSM8916 and MSM8974 to manage these as power domains. For compatibility with old device trees we still need to support falling back to the regulators when necessary. The way this is implemented here is that the deprecated regulators are defined as "fallback_proxy_supply". Only if attaching the power domains fails because they are not specified (-ENODATA) we request and manage the fallback regulators instead.
