pulsar_adc_init()

int32_t pulsar_adc_init	(	struct pulsar_adc_dev **	device,
		struct pulsar_adc_init_param *	init_param
	)

Initialize the device.

Parameters

device	- The device structure.
init_param	- The structure that contains the device initial parameters.

Returns

0 in case of success, negative error code otherwise.
