Convert existing bindings to yaml format. In the same time, remove non
exiting properties ("inj" interrupt) and add fdma.

Technically any port can serve as NPI, not just the SERDES ones. People
are even using internal PHY ports as NPI.
https://patchwork.kernel.org/project/netdevbpf/patch/20210814025003.2449143-11-colin.foster@in-advantage.com/#24381029

Honestly I would not bother talking about NPI, it is confusing to see it here.
Anything having to do with the NPI port is the realm of DSA.

Just say how the present driver expects to control the device, don't
just copy stuff from marketing slides. In this case PCIe is irrelevant
too, this driver is for a platform device, and it only runs on the
embedded processor as far as I can tell.

Above you say Microchip, and here you say Microsemi.

~powerful~

I'm pretty sure Rob will comment that this can be simplified to:

           $ref: ethernet-controller.yaml#

without the allOf: and "-".

Shouldn't there be additionalProperties: false for the port node as well?

And actually, phy-handle is not strictly required, if you have a
fixed-link. I think you should use oneOf.

And you know what else is required? phy-mode. See commits e6e12df625f2
("net: mscc: ocelot: convert to phylink") and eba54cbb92d2 ("MIPS: mscc:
ocelot: mark the phy-mode for internal PHY ports").

Ok

Ok, so I guess the binding text file was not updated back then. I'll fix
that.

Please drop this. 

emacs settings are fine, but not vim. ;) JK, I don't use either.

+description: |
+  The VSC7514 Industrial IoT Ethernet switch contains four integrated dual media
+  10/100/1000BASE-T PHYs, two 1G SGMII/SerDes, two 1G/2.5G SGMII/SerDes, and an
+  option for either a 1G/2.5G SGMII/SerDes Node Processor Interface (NPI) or a
+  PCIe interface for external CPU connectivity. The NPI/PCIe can operate as a
+  standard Ethernet port.
+
+  The device provides a rich set of Industrial Ethernet switching features such
+  as fast protection switching, 1588 precision time protocol, and synchronous
+  Ethernet. Advanced TCAM-based VLAN and QoS processing enable delivery of
+  differentiated services. Security is assured through frame processing using
+  Microsemi’s TCAM-based Versatile Content Aware Processor.
+
+  In addition, the device contains a powerful 500 MHz CPU enabling full
+  management of the switch.

-Microsemi Ocelot network Switch
-===============================
-
-The Microsemi Ocelot network switch can be found on Microsemi SoCs (VSC7513,
-VSC7514)
-
-Required properties:
-- compatible: Should be "mscc,vsc7514-switch"
-- reg: Must contain an (offset, length) pair of the register set for each
-  entry in reg-names.
-- reg-names: Must include the following entries:
-  - "sys"
-  - "rew"
-  - "qs"
-  - "ptp" (optional due to backward compatibility)
-  - "qsys"
-  - "ana"
-  - "portX" with X from 0 to the number of last port index available on that
-    switch
-- interrupts: Should contain the switch interrupts for frame extraction,
-  frame injection and PTP ready.
-- interrupt-names: should contain the interrupt names: "xtr", "inj". Can contain
-  "ptp_rdy" which is optional due to backward compatibility.
-- ethernet-ports: A container for child nodes representing switch ports.
-
-The ethernet-ports container has the following properties
-
-Required properties:
-
-- #address-cells: Must be 1
-- #size-cells: Must be 0
-
-Each port node must have the following mandatory properties:
-- reg: Describes the port address in the switch
-
-Port nodes may also contain the following optional standardised
-properties, described in binding documents:
-
-- phy-handle: Phandle to a PHY on an MDIO bus. See
-  Documentation/devicetree/bindings/net/ethernet.txt for details.
-
