17  * struct cyclecounter - hardware abstraction for a free running counter
18  *	Provides completely state-free accessors to the underlying hardware.
38  * struct timecounter - layer above a %struct cyclecounter which counts nanoseconds
41  *	timecounter_init(). Also used to convert cycle counts into the
42  *	corresponding nanosecond counts with timecounter_cyc2time(). Users
64  * cyclecounter_cyc2ns - converts cycle counter cycles to nanoseconds
75 	ns = (ns * cc->mult) + *frac;  in cyclecounter_cyc2ns()
77 	return ns >> cc->shift;  in cyclecounter_cyc2ns()
81  * timecounter_adjtime - Shifts the time of the clock.
86 	tc->nsec += delta;  in timecounter_adjtime()
90  * timecounter_init - initialize a time counter
104  * timecounter_read - return nanoseconds elapsed since timecounter_init()
114  * timecounter_cyc2time - convert a cycle counter to same
118  * @cycle_tstamp:	a value returned by tc->cc->read()
120  * Cycle counts that are converted correctly as long as they
121  * fall into the interval [-1/2 max cycle count, +1/2 max cycle count],
122  * with "max cycle count" == cs->mask+1.
