Ioana Ciornei says: ==================== dpaa2-eth: add MAC/PHY support through phylink The dpaa2-eth driver now has support for connecting to its associated PHY device found through standard OF bindings. The PHY interraction is handled by PHYLINK and even though, at the moment, only RGMII_* phy modes are supported by the driver, this is just the first step into adding the necessary changes to support the entire spectrum of capabilities. This comes after feedback on the initial DPAA2 MAC RFC submitted here: https://lwn.net/Articles/791182/ The notable change is that now, the DPMAC is not a separate driver, and communication between the DPMAC and DPNI no longer happens through firmware. Rather, the DPMAC is now a set of API functions that other net_device drivers (DPNI, DPSW, etc) can use for PHY management. The change is incremental, because the DPAA2 architecture has many modes of connecting net devices in hardware loopback (for example DPNI to DPNI). Those operating modes do not have a DPMAC and phylink instance. The documentation patch provides a more complete view of the software architecture and the current implementation. Changes in v2: - added patch 1/5 in order to fix module build - use -ENOTCONN as a proper return error of dprc_get_connection() - move the locks to rtnl outside of dpaa2_eth_[dis]connect_mac functions - remove setting supported/advertised from .validate() Changes in v3: - remove an unused variable Changes in v4: - use ERR_PTR instead of plain NULL ==================== 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.
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.
