Kishon, I still have the DT patches for BG2Q queued up for v3.19 (I missed the arm-soc merge window for v3.18). That means, there has been no release with the phy binding used and I can rework a little more. Can you please confirm that you want a DT property for the phy base address, e.g. marvell,phy-base-address = <{0x200,0x80}> ? If so, I'd also rename the compatible from berlin2q-sata-phy to more generic berlin-sata-phy.
