SPI (and others) has a way to define bus number in a aliases:

		ethernet2 = &enet2;
		ethernet3 = &enet3;
		spi0 = &spi0
	};
The 0 in the spi0 alias will translate to bus num 0 so one can control the /dev nodes, like /dev/spidev0
I am looking for the same for ethernet devices:
 ethernet4 = &enet4;  /* should become eth4 */
 ethernet0 = &enet0;  /* should become eth0 */
but I cannot find something like that for eth devices.

Could such functionality be added?

Hi Jocke

This has been discussed before. Take a look at
arch/arm/boot/dts/armada-38x.dtsi

You should be able to find the discuss about this, and why aliases
cannot be used.
