Macros
#define	NRF_CLOCK_CONTROL_FREQUENCY_MAX   UINT32_MAX
	Specifies to use the maximum available frequency for a given clock.
#define	NRF_CLOCK_CONTROL_ACCURACY_MAX   1
	Specifies to use the maximum available accuracy for a given clock.
#define	NRF_CLOCK_CONTROL_ACCURACY_PPM(ppm)
	Specifies the required clock accuracy in parts-per-million.
#define	NRF_CLOCK_CONTROL_PRECISION_HIGH   1
	Specifies that high precision of the clock is required.
#define	NRF_CLOCK_CONTROL_PRECISION_DEFAULT   0
	Specifies that default precision of the clock is sufficient.
#define	CLOCK_CONTROL_NRF_AUXPLL_GET_FREQ(node)
	Get the output frequency of an AUXPLL Devicetree node.
AUXPLL output frequencies
The AUXPLL Devicetree takes in raw register values; these are the actual output frequencies.
#define	CLOCK_CONTROL_NRF_AUXPLL_FREQ_OUT_MIN_HZ   80000000
	Minimum AUXPLL output frequency, in Hz.
#define	CLOCK_CONTROL_NRF_AUXPLL_FREQ_OUT_AUDIO_44K1_HZ   11289591
	AUXPLL output frequency for 44.1 kHz audio, in Hz.
#define	CLOCK_CONTROL_NRF_AUXPLL_FREQ_OUT_USB24M_HZ   24000000
	AUXPLL output frequency for 24 MHz USB, in Hz.
#define	CLOCK_CONTROL_NRF_AUXPLL_FREQ_OUT_AUDIO_48K_HZ   12287963
	AUXPLL output frequency for 48 kHz audio, in Hz.

Functions
static int	nrf_clock_control_request (const struct device *dev, const struct nrf_clock_spec *spec, struct onoff_client *cli)
	Request a reservation to use a given clock with specified attributes.
int	nrf_clock_control_request_sync (const struct device *dev, const struct nrf_clock_spec *spec, k_timeout_t timeout)
	Synchronously request a reservation to use a given clock with specified attributes.
static int	nrf_clock_control_release (const struct device *dev, const struct nrf_clock_spec *spec)
	Release a reserved use of a clock.
static int	nrf_clock_control_cancel_or_release (const struct device *dev, const struct nrf_clock_spec *spec, struct onoff_client *cli)
	Safely cancel a reservation request.
static int	nrf_clock_control_resolve (const struct device *dev, const struct nrf_clock_spec *req_spec, struct nrf_clock_spec *res_spec)
	Resolve a requested clock spec to resulting spec.
static int	nrf_clock_control_get_startup_time (const struct device *dev, const struct nrf_clock_spec *spec, uint32_t *startup_time_us)
	Get the startup time of a clock.
void	nrf_clock_control_hfxo_request (void)
	Request the HFXO from Zero Latency Interrupt context.
void	nrf_clock_control_hfxo_release (void)
	Release the HFXO from Zero Latency Interrupt context.
