This really doesn't seem like an optimal solution - if all that's
changed is that there's a new PLL then it should be possible to handle
that through either librification like the Samsung IISv2 block or with
runtime conditional code like the existing support for the clock
dithering on the PXA3xx.  Forking the entire driver makes maintinance
much harder.

This should be a separate patch.

seek_mclk_conf() doesn't appear to have been declared anywhere.

Why are you inverting the frame?  It shouldn't hurt but it's an odd
choice.

Remove this if it's empty.

No need to do this, pins are enaled by default.

This shouldn't be needed any more, it should get done by the core.
