xil_gpio_irq_ctrl_init()

int xil_gpio_irq_ctrl_init	(	struct no_os_irq_ctrl_desc **	desc,
		const struct no_os_irq_init_param *	param )

Initialize the GPIO IRQ controller.

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,
		struct no_os_callback_desc *	callback_desc )

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,
		enum no_os_irq_trig_level	trig )

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.

xil_gpio_irq_unregister_callback()

int xil_gpio_irq_unregister_callback	(	struct no_os_irq_ctrl_desc *	desc,
		uint32_t	irq_id,
		struct no_os_callback_desc *	cb )

Unregister pin specific GPIO interrupt.

Parameters

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

Returns

0 in case of success, -1 otherwise.
