On the CP110 unit, which can be found on various Marvell platforms such as the 7k and 8k (currently), a comphy (common PHYs) hardware block can be found. This block provides a number of PHYs which can be used in various modes by other controllers (network, SATA ...). These common PHYs must be configured for the controllers using them to work correctly either at boot time, or when the system runs to switch the mode used. This patch adds a driver for this comphy hardware block, providing callbacks for the its PHYs so that consumers can configure the modes used. As of this commit, two modes are supported by the comphy driver: sgmii and 10gkr.

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.
