Function Documentation

iio_ad559xr_aio_init()

int iio_ad559xr_aio_init	(	struct iio_ad559xr_desc **	desc,
		struct ad5592r_dev *	ad5592r )

Initialize an ad559xr iio descriptor for all ADC and DAC channels for one ad559xr device.

Parameters

[in]	desc	pointer to iio_ad559xr_desc ad559xr iio descriptor
[in]	ad5592r	pointer to ad5592r_dev

Returns

0 on success

-EINVAL when desc is NULL.

-ENODEV when ad5592r is NULL.

-ENOMEM when memory cannot be allocated.

iio_ad559xr_gpio_init()

int iio_ad559xr_gpio_init	(	struct iio_ad559xr_desc **	desc,
		struct iio_ad559xr_gpio_map *	gpio_map,
		const size_t	count )

Initialize an ad559xr iio descriptor for all GPIO channels.

This function takes an array called a gpio_map. It collects all the channels defined in all ad559xr devices declared in the gpio_map and creates one single ad559xr iio descriptor for all.

Parameters

[in]	desc	pointer to iio_ad559xr_desc ad559xr iio descriptor
[in]	gpio_map	pointer to gpio_map
[in]	count	number of gpio_maps

Returns

0 on success

-EINVAL when desc and gpio_map are both NULL.

-ENODEV when gpio_map contains an NULL ad559xr device descriptor.

iio_ad559xr_remove()

int iio_ad559xr_remove

(

struct iio_ad559xr_desc *

desc

)

Remove an ad559xr iio descriptor.

Releases memory associated with an ad559xr iio descriptor and also frees up the iio descriptor memory itself.

Parameters

[in]

desc

pointer to iio_ad559xr_desc ad559xr iio descriptor
