Required properties:
|
|
- compatible: Should be "qca,<soc>-eth". Currently support compatibles are:
|
|
qca,ar7100-eth - Atheros AR7100
|
|
qca,ar7240-eth - Atheros AR7240
|
|
qca,ar7241-eth - Atheros AR7241
|
|
qca,ar7242-eth - Atheros AR7242
|
|
qca,ar9130-eth - Atheros AR9130
|
|
qca,ar9330-eth - Atheros AR9330
|
|
qca,ar9340-eth - Atheros AR9340
|
|
qca,qca9530-eth - Qualcomm Atheros QCA9530
|
|
qca,qca9550-eth - Qualcomm Atheros QCA9550
|
|
qca,qca9560-eth - Qualcomm Atheros QCA9560
|
|
|
|
- reg : Address and length of the register set for the device
|
|
- interrupts : Should contain eth interrupt
|
|
- phy-mode : See ethernet.txt file in the same directory
|
|
- clocks: the clock used by the core
|
|
- clock-names: the names of the clock listed in the clocks property. These are
|
|
"eth" and "mdio".
|
|
- resets: Should contain phandles to the reset signals
|
|
- reset-names: Should contain the names of reset signal listed in the resets
|
|
property. These are "mac" and "mdio"
|
|
|
|
Optional properties:
|
|
- phy-handle : phandle to the PHY device connected to this device.
|
|
- fixed-link : Assume a fixed link. See fixed-link.txt in the same directory.
|
|
Use instead of phy-handle.
|
|
|
|
Optional subnodes:
|
|
- mdio : specifies the mdio bus, used as a container for phy nodes
|
|
according to phy.txt in the same directory
|
|
|
|
Example:
|
|
|
|
ethernet@1a000000 {
|
|
compatible = "qca,ar9330-eth";
|
|
reg = <0x1a000000 0x200>;
|
|
interrupts = <5>;
|
|
resets = <&rst 13>, <&rst 23>;
|
|
reset-names = "mac", "mdio";
|
|
clocks = <&pll ATH79_CLK_AHB>, <&pll ATH79_CLK_MDIO>;
|
|
clock-names = "eth", "mdio";
|
|
|
|
phy-mode = "gmii";
|
|
};
