1	* Altera Triple-Speed Ethernet MAC driver (TSE)
2	
3	Required 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	
49	Optional properties:
50	- local-mac-address: See ethernet.txt in the same directory.
51	- max-frame-size: See ethernet.txt in the same directory.
52	
53	Example:
