+* 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 it's 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".
+
+Optional properties:
+- local-mac-address: See ethernet.txt in the same directory.
+- max-frame-size: See ethernet.txt in the same directory.
