Subject: [PATCH v2 1/1] 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.
Signed-off-by: Colin Foster <colin.foster@...advantage.com>
---
v1 -> v2:
* new yaml file is now named mscc,vsc7514-serdes.yaml
* examlpes != examples
* remove "driver" name from the binding
* remove ethernet port consumer from the example
* add additionalProperties: false
* remove unnecessary, obvious sentence in the description

+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>;
- };
- };
