This is a very useful patchset, thanks!  Mitch Bradley and I have been
hooking up the mach-mmp ARM subarchitecture to it and we needed to
make a few changes, mainly because mach-mmp doesn't use COMMON_CLK.
The changes are:

1) Remove the COMMON_CLK dependency that the of_clk_* functions have by
   moving them into a new file, drivers/clk/clk-of.c.  The OF functions
   in drivers/clk/clk.c aren't dependent on anything else in clk.c
   (since you pass them a struct clk) so they can be moved out easily.
   The of_clk_* entries in clk-provider.h move to clk.h.

2) Use alloc_bootmem() instead of kzalloc() in of_clk_add_provider(),
   because we need to set up clocks during .init_early on ARM (which
   happens pre-slab) so that they are available for platform init.

I'll send our patches in a reply to this mail.  Are you okay with these
changes, and would you like to include them in your patchset?

Thanks very much,

- Chris.
