Some GDSC client drivers require the GDSC mode to be switched dynamically to HW mode at runtime to gain the power benefits. Typically such client drivers require the GDSC to be brought up in SW mode initially to enable the required dependent clocks and configure the hardware to proper state. Once initial hardware set up is done, they switch the GDSC to HW mode to save power. At the end of usecase, they switch the GDSC back to SW mode and disable the GDSC. Introduce HW_CTRL_TRIGGER flag to register the set_hwmode_dev and get_hwmode_dev callbacks for GDSC's whose respective client drivers require the GDSC mode to be switched dynamically at runtime using dev_pm_genpd_set_hwmode() API.

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.
