Subject: rtc framework handles periodic irqs
From: David Brownell <david-b@xxxxxxxxxxx>
The RTC framework has an irq_set_freq() method that should be used to manage
the periodic IRQ frequency, but the current ioctl logic doesn't know how to do
that. This patch teaches it how.
This means that drivers implementing irq_set_freq() will automatically support
RTC_IRQP_{READ,SET} ioctls; that logic doesn't need duplication within the
driver.
