Hi Mike,
- @recalc_rate Recalculate the rate of this clock, by quering hardware
and/or the clock's parent. It is up to the caller to insure
that the prepare_mutex is held across this call. Returns the
calculated rate. Optional, but recommended - if this op is not
set then clock rate will be initialized to 0.
I'm still concerned, if it's NULL, why don't just retrun parent's rate if it has?
Thanks Richard
