David S. Miller 2a5ab39beb Merge branch 'mtk_eth_soc-refactoring-and-clause45'
Daniel Golle says:

====================
net: ethernet: mtk_eth_soc: refactoring and Clause 45

Rework value and type of mdio read and write functions in mtk_eth_soc
and generally clean up and unify both functions.
Then add support to access Clause 45 phy registers, using newly
introduced helper inline functions added by a patch Russell King has
suggested in a reply to an earlier version of this series [1].

All three commits are tested on the Bananapi BPi-R64 board having
MediaTek MT7531BE DSA gigE switch using clause 22 MDIO and
Ubiquiti UniFi 6 LR access point having Aquantia AQR112C PHY using
clause 45 MDIO.

v11: also address return value of mtk_mdio_busy_wait
v10: correct order of SoB lines in 2/3, change patch order in series
v9: improved formatting and Cc missing maintainer
v8: add patch from Russel King, switch to bitfield helper macros
v7: remove unneeded variables and order OR-ed call parameters
v6: further clean up functions and more cleanly separate patches
v5: fix wrong variable name in first patch covered by follow-up patch
v4: clean-up return values and types, split into two commits
v3: return -1 instead of 0xffff on error in _mtk_mdio_write
v2: use MII_DEVADDR_C45_SHIFT and MII_REGADDR_C45_MASK to extract
    device id and register address. Unify read and write functions to
    have identical types and parameter names where possible as we are
    anyway already replacing both function bodies.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

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.
