* NI XGE Ethernet controller
Required properties:
- compatible: Should be "ni,xge-enet-3.00", but can be "ni,xge-enet-2.00" for
older device trees with DMA engines co-located in the address map,
with the one reg entry to describe the whole device.
- 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
"dma": DMA engine control and status region
"ctrl": MDIO and PHY control and status region
- interrupts: Should contain tx and rx interrupt
- interrupt-names: Should be "rx" and "tx"
- phy-mode: See ethernet.txt file in the same directory.
- nvmem-cells: Phandle of nvmem cell containing the MAC address
- nvmem-cell-names: Should be "address"
Optional properties:
- mdio subnode to indicate presence of MDIO controller
- fixed-link : Assume a fixed link. See fixed-link.txt in the same directory.
Use instead of phy-handle.
- phy-handle: See ethernet.txt file in the same directory.
Examples (10G generic PHY):
nixge0: ethernet@40000000 {
compatible = "ni,xge-enet-3.00";
reg = <0x40000000 0x4000
0x41002000 0x2000>;
reg-names = "dma", "ctrl";
nvmem-cells = <ð1_addr>;
nvmem-cell-names = "address";
interrupts = <0 29 IRQ_TYPE_LEVEL_HIGH>, <0 30 IRQ_TYPE_LEVEL_HIGH>;
interrupt-names = "rx", "tx";
interrupt-parent = <&intc>;
phy-mode = "xgmii";
phy-handle = <ðernet_phy1>;
mdio {
ethernet_phy1: ethernet-phy@4 {
compatible = "ethernet-phy-ieee802.3-c45";
reg = <4>;
};
};
};
Examples (10G generic PHY, no MDIO):
nixge0: ethernet@40000000 {
compatible = "ni,xge-enet-2.00";
reg = <0x40000000 0x6000>;
nvmem-cells = <ð1_addr>;
nvmem-cell-names = "address";
interrupts = <0 29 IRQ_TYPE_LEVEL_HIGH>, <0 30 IRQ_TYPE_LEVEL_HIGH>;
interrupt-names = "rx", "tx";
interrupt-parent = <&intc>;
phy-mode = "xgmii";
phy-handle = <ðernet_phy1>;
};
Examples (1G generic fixed-link + MDIO):
nixge0: ethernet@40000000 {
compatible = "ni,xge-enet-2.00";
reg = <0x40000000 0x6000>;
nvmem-cells = <ð1_addr>;
nvmem-cell-names = "address";
interrupts = <0 29 IRQ_TYPE_LEVEL_HIGH>, <0 30 IRQ_TYPE_LEVEL_HIGH>;
interrupt-names = "rx", "tx";
interrupt-parent = <&intc>;
phy-mode = "xgmii";
fixed-link {
speed = <1000>;
pause;
link-gpios = <&gpio0 63 GPIO_ACTIVE_HIGH>;
};
mdio {
ethernet_phy1: ethernet-phy@4 {
compatible = "ethernet-phy-ieee802.3-c22";
reg = <4>;
};
};
};
