	Read the currently active configuration of pll_id.
static void	pll_config_write (const struct pll_config *cfg, unsigned int pll_id)
	Activate the configuration cfg on pll_id.
static void	pll_enable (const struct pll_config *cfg, unsigned int pll_id)
	Activate the configuration cfg and enable PLL pll_id.
static void	pll_disable (unsigned int pll_id)
	Disable the PLL identified by pll_id.
static status_t	pll_wait_for_lock (unsigned int pll_id)
	Wait for PLL pll_id to become locked.
PLL configuration

#define	pll_get_default_rate(pll_id)
	Get the default rate in Hz of pll_id.
#define	pll_config_defaults(cfg, pll_id)
	Initialize PLL configuration using default parameters.
static void	pll_config_init (struct pll_config *cfg, enum pll_source src, unsigned int div, unsigned int mul)
