From: Rafał Miłecki <rafal@xxxxxxxxxx>
This helps validating DTS files.
Introduced example binding changes:
1. Fixed reg formatting
2. Swapped #address-cells and #size-cells incorrect values
3. Renamed node: s/phy/ethernet-phy/
Signed-off-by: Rafał Miłecki <rafal@xxxxxxxxxx>

I've verified this new binding using:
make dt_binding_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/net/brcm,unimac-mdio.yaml

-* Broadcom UniMAC MDIO bus controller
-
-Required properties:
-- compatible: should one from "brcm,genet-mdio-v1", "brcm,genet-mdio-v2",
- "brcm,genet-mdio-v3", "brcm,genet-mdio-v4", "brcm,genet-mdio-v5" or
- "brcm,unimac-mdio"
-- reg: address and length of the register set for the device, first one is the
- base register, and the second one is optional and for indirect accesses to
- larger than 16-bits MDIO transactions
-- reg-names: name(s) of the register must be "mdio" and optional "mdio_indir_rw"
-- #size-cells: must be 1
-- #address-cells: must be 0
-
-Optional properties:
-- interrupts: must be one if the interrupt is shared with the Ethernet MAC or
- Ethernet switch this MDIO block is integrated from, or must be two, if there
- are two separate interrupts, first one must be "mdio done" and second must be
- for "mdio error"
-- interrupt-names: must be "mdio_done_error" when there is a share interrupt fed
- to this hardware block, or must be "mdio_done" for the first interrupt and
- "mdio_error" for the second when there are separate interrupts
-- clocks: A reference to the clock supplying the MDIO bus controller
-- clock-frequency: the MDIO bus clock that must be output by the MDIO bus
- hardware, if absent, the default hardware values are used
-
-Child nodes of this MDIO bus controller node are standard Ethernet PHY device
-nodes as described in Documentation/devicetree/bindings/net/phy.txt
-
-Example:
-
-mdio@403c0 {
- compatible = "brcm,unimac-mdio";
- reg = <0x403c0 0x8 0x40300 0x18>;
- reg-names = "mdio", "mdio_indir_rw";
- #size-cells = <1>;
- #address-cells = <0>;
-
- ...
- phy@0 {
- compatible = "ethernet-phy-ieee802.3-c22";
- reg = <0>;
- };
-};
