The hibernation mode of Atheros AR803x PHYs defaults to be enabled after hardware reset. When the cable is unplugged, the PHY will enter hibernation mode after about 10 seconds and the PHY clocks will be stopped to save power. However, some MACs need the phy output clock for proper functioning of their logic. For instance, stmmac needs the RX_CLK of PHY for software reset to complete. Therefore, add a DT property to configure the PHY to disable this hardware hibernation mode.

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.
