* Socionext AVE ethernet controller
|
||||
|
||||
This describes the devicetree bindings for AVE ethernet controller
|
||||
implemented on Socionext UniPhier SoCs.
|
||||
|
||||
Required properties:
|
||||
- compatible: Should be
|
||||
- "socionext,uniphier-pro4-ave4" : for Pro4 SoC
|
||||
- "socionext,uniphier-pxs2-ave4" : for PXs2 SoC
|
||||
- "socionext,uniphier-ld11-ave4" : for LD11 SoC
|
||||
- "socionext,uniphier-ld20-ave4" : for LD20 SoC
|
||||
- "socionext,uniphier-pxs3-ave4" : for PXs3 SoC
|
||||
- reg: Address where registers are mapped and size of region.
|
||||
- interrupts: Should contain the MAC interrupt.
|
||||
- phy-mode: See ethernet.txt in the same directory. Allow to choose
|
||||
"rgmii", "rmii", "mii", or "internal" according to the PHY.
|
||||
The acceptable mode is SoC-dependent.
|
||||
- phy-handle: Should point to the external phy device.
|
||||
See ethernet.txt file in the same directory.
|
||||
- clocks: A phandle to the clock for the MAC.
|
||||
For Pro4 SoC, that is "socionext,uniphier-pro4-ave4",
|
||||
another MAC clock, GIO bus clock and PHY clock are also required.
|
||||
- clock-names: Should contain
|
||||
- "ether", "ether-gb", "gio", "ether-phy" for Pro4 SoC
|
||||
- "ether" for others
|
||||
- resets: A phandle to the reset control for the MAC. For Pro4 SoC,
|
||||
GIO bus reset is also required.
|
||||
- reset-names: Should contain
|
||||
- "ether", "gio" for Pro4 SoC
|
||||
- "ether" for others
|
||||
- socionext,syscon-phy-mode: A phandle to syscon with one argument
|
||||
that configures phy mode. The argument is the ID of MAC instance.
|
||||
|
||||
The MAC address will be determined using the optional properties
|
||||
defined in ethernet.txt.
|
||||
|
||||
Required subnode:
|
||||
- mdio: A container for child nodes representing phy nodes.
|
||||
See phy.txt in the same directory.
|
||||
|
||||
Example:
|
||||
|
||||
ether: ethernet@65000000 {
|
||||
compatible = "socionext,uniphier-ld20-ave4";
|
||||
reg = <0x65000000 0x8500>;
|
||||
interrupts = <0 66 4>;
|
||||
phy-mode = "rgmii";
|
||||
phy-handle = <ðphy>;
|
||||
clock-names = "ether";
|
||||
clocks = <&sys_clk 6>;
|
||||
reset-names = "ether";
|
||||
resets = <&sys_rst 6>;
|
||||
socionext,syscon-phy-mode = <&soc_glue 0>;
|
||||
local-mac-address = [00 00 00 00 00 00];
|
||||
|
||||
mdio {
|
||||
#address-cells = <1>;
|
||||
#size-cells = <0>;
|
||||
|
||||
ethphy: ethphy@1 {
|
||||
reg = <1>;
|
||||
};
|
||||
};
|
||||
};
