If you don't have the clk API configured, you have no clocks to control. So, why not make clk_get() return NULL, and make the rest of the API calls do nothing? That's what you'll end up codifying in the drivers anyway.
Ok. We can return NULL from calls that return clk *. What about other routines that return integers. Like, clk_enable(). Is returning 0 correct? Which would mean we were able to enable clk, but actually we haven't. -- viresh
