V3->V4 : No changes
V2->V3:
- Moved allOf below required
- Removed unnedded reg/reg-names in the properties section
- Removed stray minItems
V1->V2:
- Removed unnedded maxItems
- Added missing minItems
- Fixed typos in some properties names
- Fixed the mdio subnode definition

-* Altera Triple-Speed Ethernet MAC driver (TSE)
-
-Required properties:
-- compatible: Should be "altr,tse-1.0" for legacy SGDMA based TSE, and should
- be "altr,tse-msgdma-1.0" for the preferred MSGDMA based TSE.
- ALTR is supported for legacy device trees, but is deprecated.
- altr should be used for all new designs.
-- reg: Address and length of the register set for the device. It contains
- the information of registers in the same order as described by reg-names
-- reg-names: Should contain the reg names
- "control_port": MAC configuration space region
- "tx_csr": xDMA Tx dispatcher control and status space region
- "tx_desc": MSGDMA Tx dispatcher descriptor space region
- "rx_csr" : xDMA Rx dispatcher control and status space region
- "rx_desc": MSGDMA Rx dispatcher descriptor space region
- "rx_resp": MSGDMA Rx dispatcher response space region
- "s1": SGDMA descriptor memory
-- interrupts: Should contain the TSE interrupts and its mode.
-- interrupt-names: Should contain the interrupt names
- "rx_irq": xDMA Rx dispatcher interrupt
- "tx_irq": xDMA Tx dispatcher interrupt
-- rx-fifo-depth: MAC receive FIFO buffer depth in bytes
-- tx-fifo-depth: MAC transmit FIFO buffer depth in bytes
-- phy-mode: See ethernet.txt in the same directory.
-- phy-handle: See ethernet.txt in the same directory.
-- phy-addr: See ethernet.txt in the same directory. A configuration should
- include phy-handle or phy-addr.
-- altr,has-supplementary-unicast:
- If present, TSE supports additional unicast addresses.
- Otherwise additional unicast addresses are not supported.
-- altr,has-hash-multicast-filter:
- If present, TSE supports a hash based multicast filter.
- Otherwise, hash-based multicast filtering is not supported.
-
-- mdio device tree subnode: When the TSE has a phy connected to its local
- mdio, there must be device tree subnode with the following
- required properties:
-
- - compatible: Must be "altr,tse-mdio".
- - #address-cells: Must be <1>.
- - #size-cells: Must be <0>.
-
- For each phy on the mdio bus, there must be a node with the following
- fields:
-
- - reg: phy id used to communicate to phy.
- - device_type: Must be "ethernet-phy".
-
-The MAC address will be determined using the optional properties defined in
-ethernet.txt.
-
-Example:
-
