Typedef Documentation

◆ nxp_flexio_child_isr_t

nxp_flexio_child_isr_t

Callback API to inform API user that FlexIO triggered interrupt.

This callback is called from IRQ context.

Function Documentation

◆ nxp_flexio_child_attach()

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

Attach flexio child to flexio controller.

Parameters
devPointer to the device structure for the FlexIO driver instance
childPointer to flexio child
Return values
0if successful
-ENOBUFSif there are not enough available resources

◆ nxp_flexio_get_rate()

int nxp_flexio_get_rate ( const struct device dev,
uint32_t rate 
)

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

Parameters
devPointer to the device structure for the FlexIO driver instance
[out]rateSubsystem clock rate
Return values
0on successful rate reading.
-EAGAINif rate cannot be read. Some drivers do not support returning the rate when the clock is off.
-ENOTSUPif reading the clock rate is not supported for the given sub-system.
-ENOSYSif the interface is not implemented.

◆ nxp_flexio_irq_disable()

void nxp_flexio_irq_disable ( const struct device dev)

Disable FlexIO IRQ.

Parameters
devPointer to the device structure for the FlexIO driver instance

◆ nxp_flexio_irq_enable()

void nxp_flexio_irq_enable ( const struct device dev)

Enable FlexIO IRQ.

Parameters
devPointer to the device structure for the FlexIO driver instance

◆ nxp_flexio_lock()

void nxp_flexio_lock ( const struct device dev)

Lock FlexIO mutex.

Parameters
devPointer to the device structure for the FlexIO driver instance

◆ nxp_flexio_unlock()

void nxp_flexio_unlock ( const struct device dev)

Unlock FlexIO mutex.

Parameters
devPointer to the device structure for the FlexIO driver instance
