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 its 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 The MAC address will be determined using the optional properties defined in
50 ethernet.txt.
