mainlining shenanigans

NeilBrown: this patch originally contained soc-mt7620.c but as I cannot test that, I removed it. Some functions from mdio-mt7620.c are needed for soc-mt7621.c support - fixed mt7620_has_carrier() to read correct register. Original comment: Add support for SoCs from the mt7620 family. These all have one dedicated external gbit port and a builtin 5 port 100mbit switch. Additionally one of the 5 switch ports can be changed to become an additional gbit port that we can attach a phy to. MT7620 was the first SoC released after Ralink was acquired by MTK and has seen a lot of changes to the core. With MT7620 we have seen the addition of some advanced features such as TX vlan offloading, RX scatter gather and TSO. Newer MTK SoCs are based on this design. Although the builtin MT7530 is gbit capable, the builtin PHYs are only 100mbit. There are boards in the wild that use one of the gbit MACs to attach an external MT7530. For this to work a few hacks need to be applied to reorganize the MDIO address mappings and autopolling for the SoC to correctly work with the external switch. This is however not part of the series and will be part of a later series once we evaluated if we want to use DSA or switchdev.

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.
