* Amlogic Meson DWMAC Ethernet controller
|
|
|
|
The device inherits all the properties of the dwmac/stmmac devices
|
|
described in the file stmmac.txt in the current directory with the
|
|
following changes.
|
|
|
|
Required properties on all platforms:
|
|
|
|
- compatible: Depending on the platform this should be one of:
|
|
- "amlogic,meson6-dwmac"
|
|
- "amlogic,meson8b-dwmac"
|
|
- "amlogic,meson-gxbb-dwmac"
|
|
- "amlogic,meson-axg-dwmac"
|
|
Additionally "snps,dwmac" and any applicable more
|
|
detailed version number described in net/stmmac.txt
|
|
should be used.
|
|
|
|
- reg: The first register range should be the one of the DWMAC
|
|
controller. The second range is is for the Amlogic specific
|
|
configuration (for example the PRG_ETHERNET register range
|
|
on Meson8b and newer)
|
|
|
|
Required properties on Meson8b and newer:
|
|
- clock-names: Should contain the following:
|
|
- "stmmaceth" - see stmmac.txt
|
|
- "clkin0" - first parent clock of the internal mux
|
|
- "clkin1" - second parent clock of the internal mux
|
|
|
|
|
|
Example for Meson6:
|
|
|
|
ethmac: ethernet@c9410000 {
|
|
compatible = "amlogic,meson6-dwmac", "snps,dwmac";
|
|
reg = <0xc9410000 0x10000
|
|
0xc1108108 0x4>;
|
|
interrupts = <0 8 1>;
|
|
interrupt-names = "macirq";
|
|
clocks = <&clk81>;
|
|
clock-names = "stmmaceth";
|
|
}
|
|
|
|
Example for GXBB:
|
|
ethmac: ethernet@c9410000 {
|
|
compatible = "amlogic,meson-gxbb-dwmac", "snps,dwmac";
|
|
reg = <0x0 0xc9410000 0x0 0x10000>,
|
|
<0x0 0xc8834540 0x0 0x8>;
|
|
interrupts = <0 8 1>;
|
|
interrupt-names = "macirq";
|
|
clocks = <&clkc CLKID_ETH>,
|
|
<&clkc CLKID_FCLK_DIV2>,
|
|
<&clkc CLKID_MPLL2>;
|
|
clock-names = "stmmaceth", "clkin0", "clkin1";
|
|
phy-mode = "rgmii";
|
|
status = "disabled";
|
|
};
