Subject: [PATCH v3 net-next 12/14] dt-bindings: net: dsa: ocelot: add ocelot-ext documentation
The ocelot-ext driver is another sub-device of the Ocelot / Felix driver
system, which currently supports the four internal copper phys.
Signed-off-by: Colin Foster <colin.foster@...advantage.com>

v3
* Remove "currently supported" verbage
The Seville and Felix 9959 all list their supported modes following
the sentence "The following PHY interface types are supported".
During V2, I had used "currently supported" to suggest more interface
modes are around the corner, though this had raised questions.
The suggestion was to drop the entire sentence. I did leave the
modified sentence there because it exactly matches the other two
supported products.
v2
* New patch
