* Oxford Semiconductor OXNAS 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: For the OX820 SoC, it should be :
|
- "oxsemi,ox820-dwmac" to select glue
|
- "snps,dwmac-3.512" to select IP version.
|
|
- clocks: Should contain phandles to the following clocks
|
- clock-names: Should contain the following:
|
- "stmmaceth" for the host clock - see stmmac.txt
|
- "gmac" for the peripheral gate clock
|
|
- oxsemi,sys-ctrl: a phandle to the system controller syscon node
|
|
Example :
|
|
etha: ethernet@40400000 {
|
compatible = "oxsemi,ox820-dwmac", "snps,dwmac-3.512";
|
reg = <0x40400000 0x2000>;
|
interrupts = <GIC_SPI 8 IRQ_TYPE_LEVEL_HIGH>,
|
<GIC_SPI 17 IRQ_TYPE_LEVEL_HIGH>;
|
interrupt-names = "macirq", "eth_wake_irq";
|
mac-address = [000000000000]; /* Filled in by U-Boot */
|
phy-mode = "rgmii";
|
|
clocks = <&stdclk CLK_820_ETHA>, <&gmacclk>;
|
clock-names = "gmac", "stmmaceth";
|
resets = <&reset RESET_MAC>;
|
|
/* Regmap for sys registers */
|
oxsemi,sys-ctrl = <&sys>;
|
|
};
