Detailed Description

Interfaces for NXP FlexIO.

Typedef Documentation

nxp_flexio_child_isr_t

typedef int(* nxp_flexio_child_isr_t) (void *user_data)

#include <zephyr/drivers/misc/nxp_flexio/nxp_flexio.h>

Callback API to inform API user that FlexIO triggered interrupt.

The controller calls this from IRQ context whenever one of the child's mapped shifters or timers has a pending and enabled interrupt.

Parameters

user_data

Opaque pointer provided at attachment time.

Function Documentation

nxp_flexio_child_attach()

int nxp_flexio_child_attach	(	const struct device *	dev,
		const struct nxp_flexio_child *	child )

#include <zephyr/drivers/misc/nxp_flexio/nxp_flexio.h>

Attach flexio child to flexio controller.

Parameters

dev	Pointer to the device structure for the FlexIO driver instance
child	Pointer to flexio child

Return values

0	if successful
-ENOBUFS	if there are not enough available resources

nxp_flexio_get_rate()

int nxp_flexio_get_rate	(	const struct device *	dev,
		uint32_t *	rate )

#include <zephyr/drivers/misc/nxp_flexio/nxp_flexio.h>

Obtain the clock rate of sub-system used by the FlexIO.

Parameters

	dev	Pointer to the device structure for the FlexIO driver instance
[out]	rate	Subsystem clock rate

Return values

0	on successful rate reading.
-EAGAIN	if rate cannot be read. Some drivers do not support returning the rate when the clock is off.
-ENOTSUP	if reading the clock rate is not supported for the given sub-system.
-ENOSYS	if the interface is not implemented.
