There is no fn needed for dove, but kirkwood will need one IIRC.
Moreover, you could hook-up PHY-gate as a parent of corresponding
clk-gate and they will be enabled/disabled simultaneously.

But I'd prefer the driver to take care of clks _and_ PHYs.

One more: I suggest to clean the clk names of orion platforms,
they are a mess ;) And IMHO clks should always have both strings
set, e.g. kirkwood-i2s has an extclk input besides it on-chip clk.
