Heiner Kallweit says: ==================== net: phy: improve PM handling of PHY/MDIO Current implementation of MDIO bus PM ops doesn't actually implement bus-specific PM ops but just calls PM ops defined on a device level what doesn't seem to be fully in line with the core PM model. When looking e.g. at __device_suspend() the PM core looks for PM ops of a device in a specific order: 1. device PM domain 2. device type 3. device class 4. device bus I think it has good reason that there's no PM ops on device level. The situation can be improved by modeling PHY's as device type of a MDIO device. If for some other type of MDIO device PM ops are needed, it could be modeled as struct device_type as well. ==================== Tested-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.

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.
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.
