These patches backport support for the ARMADA 3700 COMPHY driver.
Also backported is the mvneta driver. This will allow switching
the SGMII speed using SMC calls. To support this you must update
the firmware using Marvells 18.12 version (this has now been
upstreamed). The mvneta driver allows 2500basex and 2500baset.
