Subject: [RFC v4 net-next 15/17] dt-bindings: net: dsa: ocelot: add ocelot-ext documentation
The ocelot-ext driver is another sub-device of the Ocelot / Felix driver
system. It requires a register array similar to the VSC7514 and has
different ports layout than existing devices.
Signed-off-by: Colin Foster <colin.foster@...advantage.com>

v4
* Add documentation for all supported modes (qsgmii / sgmii)
* /s/7412/7512
* Changes to match the VSC7514 device tree, including:
- Replace ethernet-switch@0 to ethernet-switch@...10000
- Add all reg / reg-names entries
* Add example entries for ports 4-7, which requires phy-ocelot-serdes.h
* Add the last sentence to the commit description, which replaces
the phrase "which currently supports the four internal copper
phys"
* Remove "spi {" node from the documentation
* Remove "cpu" label from port 0
* Add "soc { reg = <0 0>;" to fix dt_binding_check warning
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

+ VSC7512 (Ocelot-Ext):
+
+ The Ocelot family consists of four devices, the VSC7511, VSC7512, VSC7513,
+ and the VSC7514. The VSC7513 and VSC7514 both have an internal MIPS
+ processor that natively support Linux. Additionally, all four devices
+ support control over external interfaces, SPI and PCIe. The Ocelot-Ext
+ driver is for the external control portion.
+
+ The following PHY interface types are supported:
+
+ - phy-mode = "internal": on ports 0, 1, 2, 3
+ - phy-mode = "sgmii": on ports 4, 5, 7, 8, 9, 10
