Add combo phy driver for HiSilicon STB SoCs. This phy can be used as pcie-phy, sata-phy or usb-phy. Changes for v5: - Add bindings doc for Hi3798CV200 peripheral controller, and refer to the bindings of this parent node in combphy bindings doc. Changes for v4: - Instead of relying on device id, add a new property hisilicon,fixed-mode for combphy device that doesn't support mode select but a fixed phy mode. - Move combphy mode select register bits definition to device tree, as it may vary from one device to another. Changes for v3: - Make combphy device be child of peripheral controller and use 'reg' property for mapping combphy configuration registers. - Kill "hisilicon,peripheral-syscon" property, since parent node is just the syscon controller now. - Check combphy id to handle the quirk that combphy0 can not configure mode but always works in USB3 mode. - Unify phy .init and .exit hooks for different combphy instances and work modes, as the only quirk we need to handle is that combphy0 can only work in USB3 mode. - Better naming for clock and reset, 'ref' to 'ref_clk', 'por' to 'por_rst'. Changes for v2: - Move DT bindings into a separate patch. - Drop the spurious newline from drivers/phy/Makefile. - Use the phy type defines in dt-bindings/phy/phy.h. - Use PTR_ERR_OR_ZERO() for checking return from devm_of_phy_provider_register(). - Add USB3 phy support.

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.
