1* Altera Triple-Speed Ethernet MAC driver (TSE)
2
3Required properties:
4- compatible: Should be "altr,tse-1.0" for legacy SGDMA based TSE, and should
5		be "altr,tse-msgdma-1.0" for the preferred MSGDMA based TSE.
6		ALTR is supported for legacy device trees, but is deprecated.
7		altr should be used for all new designs.
8- reg: Address and length of the register set for the device. It contains
9  the information of registers in the same order as described by reg-names
10- reg-names: Should contain the reg names
11  "control_port": MAC configuration space region
12  "tx_csr":       xDMA Tx dispatcher control and status space region
13  "tx_desc":      MSGDMA Tx dispatcher descriptor space region
14  "rx_csr" :      xDMA Rx dispatcher control and status space region
15  "rx_desc":      MSGDMA Rx dispatcher descriptor space region
16  "rx_resp":      MSGDMA Rx dispatcher response space region
17  "s1":		  SGDMA descriptor memory
18- interrupts: Should contain the TSE interrupts and it's mode.
19- interrupt-names: Should contain the interrupt names
20  "rx_irq":       xDMA Rx dispatcher interrupt
21  "tx_irq":       xDMA Tx dispatcher interrupt
22- rx-fifo-depth: MAC receive FIFO buffer depth in bytes
23- tx-fifo-depth: MAC transmit FIFO buffer depth in bytes
24- phy-mode: See ethernet.txt in the same directory.
25- phy-handle: See ethernet.txt in the same directory.
26- phy-addr: See ethernet.txt in the same directory. A configuration should
27		include phy-handle or phy-addr.
28- altr,has-supplementary-unicast:
29		If present, TSE supports additional unicast addresses.
30		Otherwise additional unicast addresses are not supported.
31- altr,has-hash-multicast-filter:
32		If present, TSE supports a hash based multicast filter.
33		Otherwise, hash-based multicast filtering is not supported.
34
35- mdio device tree subnode: When the TSE has a phy connected to its local
36		mdio, there must be device tree subnode with the following
37		required properties:
38
39	- compatible: Must be "altr,tse-mdio".
40	- #address-cells: Must be <1>.
41	- #size-cells: Must be <0>.
42
43	For each phy on the mdio bus, there must be a node with the following
44	fields:
45
46	- reg: phy id used to communicate to phy.
47	- device_type: Must be "ethernet-phy".
48
49Optional properties:
50- local-mac-address: See ethernet.txt in the same directory.
51- max-frame-size: See ethernet.txt in the same directory.
