     * 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.
