Function Documentation

◆ lt7182s_iio_init()

int lt7182s_iio_init	(	struct lt7182s_iio_desc **	iio_desc,
		struct lt7182s_iio_desc_init_param *	init_param
	)

Initializes the LT7182S IIO descriptor.

Parameters

iio_desc	- The iio device descriptor.
init_param	- The structure that contains the device initial parameters.

Returns: 0 in case of success, an error code otherwise.

Here is the caller graph for this function:

◆ lt7182s_iio_remove()

int lt7182s_iio_remove ( struct lt7182s_iio_desc * iio_desc )
