[v6,net-next,00/10] dt-binding preparation for ocelot switches

Message

Ocelot switches have the abilitiy to be used internally via
memory-mapped IO or externally via SPI or PCIe. This brings up issues
for documentation, where the same chip might be accessed internally in a
switchdev manner, or externally in a DSA configuration. This patch set
is perparation to bring DSA functionality to the VSC7512, utilizing as
much as possible with an almost identical VSC7514 chip.

This patch set changed quite a bit from v2, so I'll omit the background
of how those sets came to be. Rob offered a lot of very useful guidance.
My thanks.

At the end of the day, with this patch set, there should be a framework
to document Ocelot switches (and any switch) in scenarios where they can
be controlled internally (ethernet-switch) or externally (dsa-switch).

v5 -> v6
  * Rebase so it applies to net-next cleanly.
  * No other changes - during the last submission round I said I'd
    submit v6 with a change to move $dsa-port.yaml to outside the allOf
    list. In retrospect that wasn't the right thing to do, because later
    in the patch series the $dsa-port.yaml is removed outright. So I
    believe the submission in v5 to keep "type: object" was correct.

v4 -> v5
  * Sync DSA maintainers with MAINTAINERS file (new patch 1)
  * Undo move of port description of mediatek,mt7530.yaml (patch 4)
  * Move removal of "^(ethernet-)?switch(@.*)?$" in dsa.yaml from patch 4
    to patch 8
  * Add more consistent capitalization in title lines and better Ethernet
    switch port description. (patch 8)

v3 -> v4
  * Renamed "base" to "ethernet-ports" to avoid confusion with the concept
    of a base class.
  * Squash ("dt-bindings: net: dsa: mediatek,mt7530: fix port description location")
    patch into ("dt-bindings: net: dsa: utilize base definitions for standard dsa
    switches")
  * Corrections to fix confusion about additonalProperties vs unevaluatedProperties.
    See specific patches for details.

v2 -> v3
  * Restructured everything to use a "base" iref for devices that don't
    have additional properties, and simply a "ref" for devices that do.
  * New patches to fix up brcm,sf2, qca8k, and mt7530
  * Fix unevaluatedProperties errors from previous sets (see specific
    patches for more detail)
  * Removed redundant "Device Tree Binding" from titles, where applicable.

v1 -> v2
  * Two MFD patches were brought into the MFD tree, so are dropped
  * Add first patch 1/6 to allow DSA devices to add ports and port
    properties
  * Test qca8k against new dt-bindings and fix warnings. (patch 2/6)
  * Add tags (patch 3/6)
  * Fix vsc7514 refs and properties
