The GPIO polarity passed to phy-reset-gpio is ignored by the FEC driver and it is assumed to be active low. It can be active high only when the 'phy-reset-active-high' property is present. The current examples pass active high polarity and work fine, but in order to improve the documentation make it explicit what the real polarity is.

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.
