Function Documentation

irq_disable_next_level()

static void irq_disable_next_level ( const struct device * dev, uint32_t irq )

inlinestatic

Disable an IRQ in the next level.

This routine disables interrupts present in the interrupt controller.

Parameters

dev	Pointer to the device structure for the driver instance.
irq	IRQ to be disabled.

irq_enable_next_level()

static void irq_enable_next_level ( const struct device * dev, uint32_t irq )

inlinestatic

Enable an IRQ in the next level.

This routine enables interrupts present in the interrupt controller.

Parameters

dev	Pointer to the device structure for the driver instance.
irq	IRQ to be enabled.

irq_is_enabled_next_level()

static unsigned int irq_is_enabled_next_level ( const struct device * dev )

inlinestatic

Get IRQ enable state.

This routine indicates if any interrupts are enabled in the interrupt controller.

Parameters

dev	Pointer to the device structure for the driver instance.

Returns

interrupt enable state, true or false

irq_line_is_enabled_next_level()

static unsigned int irq_line_is_enabled_next_level ( const struct device * dev, unsigned int irq )

inlinestatic

Get IRQ line enable state.

Query if a particular IRQ line is enabled.

Parameters

dev	Pointer to the device structure for the driver instance.
irq	IRQ line to be queried.

Returns

interrupt enable state, true or false

irq_set_priority_next_level()

static void irq_set_priority_next_level ( const struct device * dev, uint32_t irq, uint32_t prio, uint32_t flags )

inlinestatic

Set IRQ priority.

This routine indicates if any interrupts are enabled in the interrupt controller.

Parameters

dev	Pointer to the device structure for the driver instance.
irq	IRQ to be disabled.
prio	priority for irq in the interrupt controller.
flags	controller specific flags.
