1 * NI XGE Ethernet controller
2
3 Required properties:
4 - compatible: Should be "ni,xge-enet-3.00", but can be "ni,xge-enet-2.00" for
5 older device trees with DMA engines co-located in the address map,
6 with the one reg entry to describe the whole device.
7 - reg: Address and length of the register set for the device. It contains the
8 information of registers in the same order as described by reg-names.
9 - reg-names: Should contain the reg names
10 "dma": DMA engine control and status region
11 "ctrl": MDIO and PHY control and status region
12 - interrupts: Should contain tx and rx interrupt
13 - interrupt-names: Should be "rx" and "tx"
14 - phy-mode: See ethernet.txt file in the same directory.
15 - nvmem-cells: Phandle of nvmem cell containing the MAC address
16 - nvmem-cell-names: Should be "address"
17
18 Optional properties:
19 - mdio subnode to indicate presence of MDIO controller
20 - fixed-link : Assume a fixed link. See fixed-link.txt in the same directory.
21 Use instead of phy-handle.
22 - phy-handle: See ethernet.txt file in the same directory.
