Parameters

desc	- The GPIO IRQ controller descriptor.
param	- The GPIO IRQ controller initial parameters. irq_ctrl_id from irq_init_param is the interrupt id for the parent controller

Returns

0 in case of success, -1 otherwise.

xil_gpio_irq_ctrl_remove()

int xil_gpio_irq_ctrl_remove

(

struct no_os_irq_ctrl_desc *

desc

)

Remove the GPIO IRQ controller.

Parameters

desc	- The GPIO IRQ controller descriptor.

Returns

0 in case of success, -1 otherwise.

xil_gpio_irq_disable()

int xil_gpio_irq_disable	(	struct no_os_irq_ctrl_desc *	desc,
		uint32_t	irq_id )

Disable specific GPIO IRQ pin.

Parameters

desc	- The GPIO IRQ controller descriptor.
irq_id	- Pin number.

Returns

0 in case of success, -1 otherwise.

xil_gpio_irq_enable()

int xil_gpio_irq_enable	(	struct no_os_irq_ctrl_desc *	desc,
		uint32_t	irq_id )

Enable specific GPIO IRQ pin.

Parameters

desc	- The GPIO IRQ controller descriptor.
irq_id	- Pin number.

Returns

0 in case of success, -1 otherwise.

xil_gpio_irq_register_callback()

int xil_gpio_irq_register_callback	(	struct no_os_irq_ctrl_desc *	desc,
		uint32_t	irq_id,

Register pin specific GPIO interrupt.

Parameters

desc	- The GPIO IRQ controller descriptor.
irq_id	- Pin number.
callback_desc	- Callback.

Returns

0 in case of success, -1 otherwise.

xil_gpio_irq_trigger_level_set()

int xil_gpio_irq_trigger_level_set	(	struct no_os_irq_ctrl_desc *	desc,
		uint32_t	irq_id,

Set GPIO interrupt trigger level.

Parameters

desc	- The GPIO IRQ controller descriptor.
irq_id	- Pin number.
trig	- New trigger level for the GPIO interrupt.

Returns

0 in case of success, -1 otherwise.
