Coarse Powergating is a power saving technique where Render and Media
can be power-gated independently irrespective of the rest of the GT.
For debug purposes, it is useful to expose the powergating information.
v2: move to debugfs
add details to commit message
add per-slice status for media
define reg bits in descending order (Matt Roper)
v3: fix return statement
fix kernel-doc
use loop for media slices
use helper function for status (Michal)
v4: add pg prefix
do not wake GT if in C6 (Badal)

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.
