All EtherAVB instances on R-Car Gen3/Gen4 SoCs support the RGMII interface. In addition, the first two EtherAVB instances on R-Car V4M also support the MII interface, but this is not yet supported by the driver. Add support for MII on R-Car Gen4 by adding an R-Car Gen4-specific EMAC initialization function that selects the MII clock instead of the RGMII clock when the PHY interface is MII. Note that all implementations of EtherAVB on R-Car Gen4 SoCs have the APSR register, but only MII-capable instances are documented to have the MIISELECT bit, which has a documented value of zero when reserved.

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 reStructuredText 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.
