commit 9119570039481d56350af1c636f040fb300b8cf3 upstream.
According to upstream commit 5ec55823438e("net: stmmac:
add clocks management for gmac driver"), it improve clocks
management for stmmac driver. So, it is necessary to implement
the runtime callback in dwmac-socfpga driver because it doesn't
use the common stmmac_pltfr_pm_ops instance. Otherwise, clocks
are not disabled when system enters suspend status.

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.
