b.liue9582032025-04-17 19:18:16 +08001* Socionext NetSec Ethernet Controller IP
2
3Required properties:
4- compatible: Should be "socionext,synquacer-netsec"
5- reg: Address and length of the control register area, followed by the
6 address and length of the EEPROM holding the MAC address and
7 microengine firmware
8- interrupts: Should contain ethernet controller interrupt
9- clocks: phandle to the PHY reference clock
10- clock-names: Should be "phy_ref_clk"
11- phy-mode: See ethernet.txt file in the same directory
12- phy-handle: See ethernet.txt in the same directory.
13
14- mdio device tree subnode: When the Netsec has a phy connected to its local
15 mdio, there must be device tree subnode with the following
16 required properties:
17
18 - #address-cells: Must be <1>.
19 - #size-cells: Must be <0>.
20
21 For each phy on the mdio bus, there must be a node with the following
22 fields:
23 - compatible: Refer to phy.txt
24 - reg: phy id used to communicate to phy.
25
26Optional properties: (See ethernet.txt file in the same directory)
27- dma-coherent: Boolean property, must only be present if memory
28 accesses performed by the device are cache coherent.
29- max-speed: See ethernet.txt in the same directory.
30- max-frame-size: See ethernet.txt in the same directory.
31
32The MAC address will be determined using the optional properties
33defined in ethernet.txt.

35Example:
36 eth0: ethernet@522d0000 {
37 compatible = "socionext,synquacer-netsec";
38 reg = <0 0x522d0000 0x0 0x10000>, <0 0x10000000 0x0 0x10000>;
39 interrupts = <GIC_SPI 176 IRQ_TYPE_LEVEL_HIGH>;
40 clocks = <&clk_netsec>;
41 clock-names = "phy_ref_clk";
42 phy-mode = "rgmii";
43 max-speed = <1000>;
44 max-frame-size = <9000>;
45 phy-handle = <&phy1>;
46
47 mdio {
48 #address-cells = <1>;
49 #size-cells = <0>;
50 phy1: ethernet-phy@1 {
51 compatible = "ethernet-phy-ieee802.3-c22";
52 reg = <1>;
53 };
