drivers/rtc: remove IRQF_DISABLED

2012-03-23T23:58:39+00:00

Since commit e58aa3d2d0cc ("genirq: run irq handlers with interrupts
disabled") we run all interrupt handlers with interrupts disabled and we
even check and yell when an interrupt handler returns with interrupts
enabled - see commit b738a50a2026 ("genirq: warn when handler enables
interrupts").

So now this flag is a NOOP and can be removed.

rtc: convert drivers/rtc/* to use module_platform_driver()

2012-01-11T00:30:53+00:00

This patch converts the drivers in drivers/rtc/* to use the
module_platform_driver() macro which makes the code smaller and a bit
simpler.

RTC: Cleanup rtc_class_ops->irq_set_freq()

2011-03-09T19:23:35+00:00

With the generic rtc code now emulating PIE mode irqs via an
hrtimer, no one calls the rtc_class_ops->irq_set_freq call.

This patch removes the hook and deletes the driver functions
if no one else calls them.

RTC: Cleanup rtc_class_ops->irq_set_state

2011-03-09T19:23:34+00:00

With PIE mode interrupts now emulated in generic code via an hrtimer,
no one calls rtc_class_ops->irq_set_state(), so this patch removes it
along with driver implementations.

RTC: Convert rtc drivers to use the alarm_irq_enable method

2011-02-03T21:02:35+00:00

Some rtc drivers use the ioctl method instead of the alarm_irq_enable
method for enabling alarm interupts. With the new virtualized RTC
rework, its important for drivers to use the alarm_irq_enable instead.

This patch converts the drivers that use the AIE ioctl method to
use the alarm_irq_enable method. Other ioctl cmds are left untouched.

I have not been able to test or even compile most of these drivers.
Any help to make sure this change is correct would be appreciated!

rtc: move power of 2 periodic frequency check down into drivers

2009-01-06T23:59:24+00:00

Move the power of 2 check on frequencies down into individual rtc drivers

This is to allow for non power of 2 real time clock periodic interrupts
such as those on the pxa27x to be found in the new pxa27x-rtc driver

rtc: bunch of drivers: fix 'no irq' case handing

2009-01-06T23:59:23+00:00

This patch fixes a bunch of irq checking misuses.  Most drivers were
getting irq via platform_get_irq(), which returns -ENXIO or r->start.

rtc-cmos.c is special.  It is using PNP and platform bindings.  Hopefully
nobody is using PNP IRQ 0 for RTC.  So the changes should be safe.

rtc-sh.c is using platform_get_irq, but was storing a result into an
unsigned type, then was checking for < 0.  This is fixed now.
