Data Structures
struct	pbl_clk_cal_ops
	Gate operations, called from the tick interrupt or a thread, one gate at a time. More...
struct	pbl_clk_cal
	A calibrated clock. More...
struct	pbl_clk_cal_status
	Calibration state, for diagnostics. More...

Macros
#define	PBL_CLK_CAL_INIT(_ops, _params, _clk, _gate_cycles, _period_ms)
	Initializer for a struct pbl_clk_cal.

Functions
void	pbl_clk_cal_start (struct pbl_clk_cal *cal, double nominal_hz)
	Start the periodic gates, the first one now.
struct pbl_clk_cal *	pbl_clk_cal_find (const char *name)
	Find a calibrated clock by the name of its controller.
int	pbl_clk_cal_sample (struct pbl_clk_cal *cal, uint32_t cycles, double *hz)
	Take one raw gate, outside the periodic calibration, which waits meanwhile.
void	pbl_clk_cal_hold (struct pbl_clk_cal *cal, uint64_t rate_mhz)
	Publish a fixed rate, or the tracked one again.
void	pbl_clk_cal_get_status (const struct pbl_clk_cal *cal, struct pbl_clk_cal_status *status)
	Get the calibration state.
uint64_t	pbl_clk_cal_get_rate (const struct pbl_clk_cal *cal)
	Get the current rate.
