* 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".
|
|
|
|
The MAC address will be determined using the optional properties defined in
|
|
ethernet.txt.
|
|
|
|
