====================
New RGMII delay DT bindings for the SJA1105 DSA driver

During recent reviews I've been telling people that new MAC drivers
should adopt a certain DT binding format for RGMII delays in order to
avoid conflicting interpretations. Some suggestions were better received
than others, and it appears we are still far from a consensus.

Part of the problem seems to be that there are still drivers that apply
RGMII delays based on an incorrect interpretation of the device tree,
and these serve as a bad example for others.
I happen to maintain one of those drivers and I am able to test it, so I
figure that one of the ways in which I can make a change is to stop
providing a bad example.

Therefore, this series adds support for the "rx-internal-delay-ps" and
"tx-internal-delay-ps" properties inside sja1105 switch port DT nodes,
and if these are present, they will decide what RGMII delays will the
driver apply.

The in-tree device trees are also updated to follow the new format, as
well as the schema validator.

I assume it's okay to get all changes merged in through the same tree
(net-next). Although the DTS changes could be split, if needed - the
driver works with or without them. There is one more DTS which should be
changed, which is in Shawn's tree but not in net-next:
https://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux.git/tree/arch/arm64/boot/dts/freescale/fsl-lx2160a-bluebox3.dts?h=for-next
For that, I'd have to send a separate patch.

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.
