Hi Rob,

Just FYI I've been looking at using alloc_bootmem in the common clk code
as a way to get rid of the static initialization stuff (which only
existed due to very early initialization of timers).

The suggested change above to of_clk_add_provider would jive well with
my change to the common clk code.

Regards,
Mike
