- * 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".
- Optional properties:
- - local-mac-address: See ethernet.txt in the same directory.
- - max-frame-size: See ethernet.txt in the same directory.
