Linux kernel source tree

The PHY reset signal is controlled by bit PHYRSTZ in the MC_PHYRSTZ register. The signal is active low on Gen1 PHYs and active high on Gen2 PHYs. The driver toggles the signal high then low, which is correct for all currently supported platforms, but the register values macros are incorrectly named. Replace them with a single macro named after the bit, and add a comment to the source code to explain the behaviour. The driver's behaviour isn't changed by this rename, the code will still need to be fixed to support Gen1 PHYs.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
