Functions
int32_t	ad917x_init (ad917x_handle_t *h)
	Initialize AD917X Device This API must be called first before any other API calls. It performs internal API initialization of the memory and API states. If AD917X handle member hw_open is not NULL it shall call the function to which it points. This feature may be used to get and initialize the hardware resources required by the API and the AD917X devices. For example GPIO, SPI etc.
int32_t	ad917x_deinit (ad917x_handle_t *h)
	De-initialize the AD917X Device.
int32_t	ad917x_get_chip_id (ad917x_handle_t *h, adi_chip_id_t *chip_id)
	Get Chip Identification Data.
int32_t	ad917x_reset (ad917x_handle_t *h, uint8_t hw_reset)
	Reset the AD917X.
int32_t	ad917x_get_revision (ad917x_handle_t *h, uint8_t *rev_major, uint8_t *rev_minor, uint8_t *rev_rc)
	Get API Revision Data.
int32_t	ad917x_set_dac_pll_config (ad917x_handle_t *h, uint8_t dac_pll_en, uint8_t m_div, uint8_t n_div, uint8_t vco_div)
	Configure the On Chip DAC PLL.
int32_t	ad917x_set_dac_clk_freq (ad917x_handle_t *h, uint64_t dac_clk_freq_hz)
	Set the DAC CLK Frequency.
int32_t	ad917x_get_dac_clk_freq (ad917x_handle_t *h, uint64_t *dac_clk_freq_hz)
	Get the DAC CLK Frequency.
int32_t	ad917x_get_dac_clk_status (ad917x_handle_t *h, uint8_t *pll_lock_stat, uint8_t *dll_lock_stat)
	Get DAC CLK Status.
int32_t	ad917x_set_clkout_config (ad917x_handle_t *h, uint8_t l_div)
	Set CLKOUT configuration.
int32_t	ad917x_set_dac_clk (ad917x_handle_t *h, uint64_t dac_clk_freq_hz, uint8_t dac_pll_en, uint64_t ref_clk_freq_hz)
	Configure the DAC Clock Input path based on a the desired dac clock frequency, the applied reference clock and the onchip PLL.
int32_t	ad917x_set_page_idx (ad917x_handle_t *h, const uint32_t dac, const uint32_t channel)
	Select Page.
int32_t	ad917x_get_page_idx (ad917x_handle_t *h, int32_t *dac, int32_t *channel)
	Get select page index.
