* Socionext NetSec Ethernet Controller IP
|
|
|
|
Required properties:
|
|
- compatible: Should be "socionext,synquacer-netsec"
|
|
- reg: Address and length of the control register area, followed by the
|
|
address and length of the EEPROM holding the MAC address and
|
|
microengine firmware
|
|
- interrupts: Should contain ethernet controller interrupt
|
|
- clocks: phandle to the PHY reference clock
|
|
- clock-names: Should be "phy_ref_clk"
|
|
- phy-mode: See ethernet.txt file in the same directory
|
|
- phy-handle: See ethernet.txt in the same directory.
|
|
|
|
- mdio device tree subnode: When the Netsec has a phy connected to its local
|
|
mdio, there must be device tree subnode with the following
|
|
required properties:
|
|
|
|
- #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:
|
|
- compatible: Refer to phy.txt
|
|
- reg: phy id used to communicate to phy.
|
|
|
|
Optional properties: (See ethernet.txt file in the same directory)
|
|
- dma-coherent: Boolean property, must only be present if memory
|
|
accesses performed by the device are cache coherent.
|
|
- max-speed: See ethernet.txt in the same directory.
|
|
- max-frame-size: See ethernet.txt in the same directory.
|
|
|
|
The MAC address will be determined using the optional properties
|
|
defined in ethernet.txt.
|
|
|
|
Example:
|
|
eth0: ethernet@522d0000 {
|
|
compatible = "socionext,synquacer-netsec";
|
|
reg = <0 0x522d0000 0x0 0x10000>, <0 0x10000000 0x0 0x10000>;
|
|
interrupts = <GIC_SPI 176 IRQ_TYPE_LEVEL_HIGH>;
|
|
clocks = <&clk_netsec>;
|
|
clock-names = "phy_ref_clk";
|
|
phy-mode = "rgmii";
|
|
max-speed = <1000>;
|
|
max-frame-size = <9000>;
|
|
phy-handle = <&phy1>;
|
|
|
|
mdio {
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|
phy1: ethernet-phy@1 {
|
|
compatible = "ethernet-phy-ieee802.3-c22";
|
|
reg = <1>;
|
|
};
|
|
};
