* 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"
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";
};
