The EtherAVB instances on the R-Car E3/D3 and RZ/G2E SoCs do not support
TX clock internal delay modes, and the EtherAVB driver prints a warning
if an unsupported "rgmii-*id" PHY mode is specified, to catch buggy
DTBs.
Commit a6f51f2efa742df0 ("ravb: Add support for explicit internal
clock delay configuration") deprecated deriving the internal delay mode
from the PHY mode, in favor of explicit configuration using the now
mandatory "rx-internal-delay-ps" and "tx-internal-delay-ps" properties,
thus delegating the warning to the legacy fallback code.
Since explicit configuration of a (valid) internal clock delay
configuration is enforced by validating device tree source files against
DT binding files, and all upstream DTS files have been converted as of
commit a5200e63af57d05e ("arm64: dts: renesas: rzg2: Convert EtherAVB to
explicit delay handling"), the checks in the legacy fallback code can be
removed.

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.
