This is already available in armada-370.dtsi as ge0_rgmii_pins.

This however does not seem to be in armada-370.dtsi. This is probably
because there are a few options:
MPP_FUNCTION(0x0, "gpio", NULL),
MPP_FUNCTION(0x1, "uart0", "rxd")),
MPP_MODE(1,
MPP_FUNCTION(0x0, "gpo", NULL),
MPP_FUNCTION(0x1, "uart0", "txd")),
MPP_MODE(2,
MPP_FUNCTION(0x0, "gpio", NULL),
MPP_FUNCTION(0x1, "i2c0", "sck"),
MPP_FUNCTION(0x2, "uart0", "txd")),
MPP_MODE(3,
MPP_FUNCTION(0x0, "gpio", NULL),
MPP_FUNCTION(0x1, "i2c0", "sda"),
MPP_FUNCTION(0x2, "uart0", "rxd")),
What we found with Kirkwood, is that everybody picks the
same. Probably because of Marvell's RDK and U-boot etc. It is not
clear from the current 370 boards what is being used. I should go look
at Mirabox and 370 RD. If they are all mpp0 & mpp1, i suggest we put
this into armada-370.dtsi

Again, we might want to put this in armada-370.dtsi.

There is some logic to this naming, but i don't remember what it is.
Did you check this is appropriate?
