* 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. The 'phy-mode' property is required, but may |
|
be set to the empty string if the PHY configuration is programmed by |
|
the firmware or set by hardware straps, and needs to be preserved. |
|
|
|
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>; |
|
}; |
|
};
