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>;

		};

	};
