dt-bindings: phy: ocelot-serdes: convert to YAML

Convert the phy-ocelot-serdes device tree binding to the new YAML format.

Additionally, add the file to MAINTAINERS since the original file didn't
exist.

title: Microsemi Ocelot SerDes muxing
maintainers:
- Alexandre Belloni <alexandre.belloni@bootlin.com>
- UNGLinuxDriver@microchip.com
description: |
On Microsemi Ocelot, there is a handful of registers in HSIO address
space for setting up the SerDes to switch port muxing.
A SerDes X can be "muxed" to work with switch port Y or Z for example.
One specific SerDes can also be used as a PCIe interface.
Hence, a SerDes represents an interface, be it an Ethernet or a PCIe one.
There are two kinds of SerDes: SERDES1G supports 10/100Mbps in
half/full-duplex and 1000Mbps in full-duplex mode while SERDES6G supports
10/100Mbps in half/full-duplex and 1000/2500Mbps in full-duplex mode.
Also, SERDES6G number (aka "macro") 0 is the only interface supporting
QSGMII.
This is a child of the HSIO syscon ("mscc,ocelot-hsio", see
Documentation/devicetree/bindings/mips/mscc.txt) on the Microsemi Ocelot.

Microsemi Ocelot SerDes muxing driver
-------------------------------------
On Microsemi Ocelot, there is a handful of registers in HSIO address
space for setting up the SerDes to switch port muxing.
A SerDes X can be "muxed" to work with switch port Y or Z for example.
One specific SerDes can also be used as a PCIe interface.
Hence, a SerDes represents an interface, be it an Ethernet or a PCIe one.
There are two kinds of SerDes: SERDES1G supports 10/100Mbps in
half/full-duplex and 1000Mbps in full-duplex mode while SERDES6G supports
10/100Mbps in half/full-duplex and 1000/2500Mbps in full-duplex mode.
Also, SERDES6G number (aka "macro") 0 is the only interface supporting
QSGMII.
This is a child of the HSIO syscon ("mscc,ocelot-hsio", see
Documentation/devicetree/bindings/mips/mscc.txt) on the Microsemi Ocelot.
Required properties:
- compatible: should be "mscc,vsc7514-serdes"
- #phy-cells : from the generic phy bindings, must be 2.
The first number defines the input port to use for a given
SerDes macro. The second defines the macro to use. They are
defined in dt-bindings/phy/phy-ocelot-serdes.h
Example:
serdes: serdes {
compatible = "mscc,vsc7514-serdes";
#phy-cells = <2>;
};
ethernet {
port1 {
phy-handle = <&phy_foo>;
/* Link SERDES1G_5 to port1 */
phys = <&serdes 1 SERDES1G_5>;
};
};
