* 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.
- 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.
