     * 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.
                    For the OX810SE SoC, it should be :
                    - "oxsemi,ox810se-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>;
    
    };
