void rtc_handle_legacy_irq	(	struct rtc_device *	rtc,
		int	num,
		int	mode
	)

rtc_handle_legacy_irq - AIE, UIE and PIE event hook : pointer to the rtc device

This function is called when an AIE, UIE or PIE mode interrupt has occurred (or been emulated).

Triggers the registered irq_task function callback.

rtc_irq_set_freq - set 2^N Hz periodic IRQ frequency for IRQ : the rtc device : currently registered with rtc_irq_register() : positive frequency with which task->func() will be called Context: any

Note that rtc_irq_set_state() is used to enable or disable the periodic IRQs.

Definition at line 726 of file interface.c.

int rtc_irq_set_state	(	struct rtc_device *	rtc,

rtc_irq_set_state - enable/disable 2^N Hz periodic IRQs : the rtc device : currently registered with rtc_irq_register() : true to enable periodic IRQs Context: any

Note that rtc_irq_set_freq() should previously have been used to specify the desired frequency of periodic IRQ task->func() callbacks.

enum hrtimer_restart rtc_pie_update_irq ( struct hrtimer * timer )

rtc_pie_update_irq - PIE mode hrtimer hook : pointer to the pie mode hrtimer

This function is used to emulate PIE mode interrupts using an hrtimer. This function is called when the periodic hrtimer expires.
