The AST2600 MDIO bus controller has a reset control bit and must be deasserted before manipulating the MDIO controller. By default, the hardware asserts the reset so the driver only need to deassert it. Regarding to the old DT blobs which don't have reset property in them, the reset deassertion is usually done by the bootloader so the reset property is optional to work with them.

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.
