If enable Advance Link Down Power Saving (ALDPS) mode, it will change crystal/clock behavior, which cause RXC clock stop for dozens to hundreds of miliseconds. This is comfirmed by Realtek engineer. For some MACs, it needs RXC clock to support RX logic, after this patch, PHY can generate continuous RXC clock during auto-negotiation. ALDPS default is disabled after hardware reset, it's more reasonable to add a property to enable this feature, since ALDPS would introduce side effect. This patch adds dt property "realtek,aldps-enable" to enable ALDPS mode per users' requirement. Jisheng Zhang enables this feature, changes the default behavior. Since mine patch breaks the rule that new implementation should not break existing design, so Cc'ed let him know to see if it can be accepted.

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.
