Currently, Berlin SATA PHY driver assumes PHY_BASE address being
constant. While this PHY_BASE is correct for BG2Q, older BG2 PHY_BASE
is different. Prepare the driver for BG2 support by moving the phy_base
into private driver data.

Can't the base directly come from dt?
You are suggesting a "marvell,phy-base-address" property, right?
I have no strong opinion about it, I accept your call (or DT maintainer
ones).
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.
Sebastian
