* 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>;
};
