drivers/rtc/rtc-mpc5121.c: use platform_{get,set}_drvdata()

2013-07-03T23:07:59+00:00

Use the wrapper functions for getting and setting the driver data using
platform_device instead of using dev_{get,set}_drvdata() with &pdev->dev,
so we can directly pass a struct platform_device.

drivers/rtc: use of_match_ptr() macro

2013-02-22T01:22:27+00:00

This eliminates having an #ifdef returning NULL for the case when OF is
disabled.  Maintains consistency in cases where OF is always selected.

Drivers: rtc: remove __dev* attributes.

2013-01-03T23:57:02+00:00

CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

rtc: Fix possible null pointer dereference in rtc-mpc5121.c

2012-04-26T09:17:01+00:00

Mark Loard pointed out:
"For example, this beauty from rtc-mpc5121.c in the same update:
   ...
   rtc->rtc = rtc_device_register("mpc5200-rtc", &op->dev,
                                   &mpc5200_rtc_ops, THIS_MODULE);
   ...

   rtc->rtc->uie_unsupported = 1;    // <<<< Ooops NULL pointer >>>>

   if (IS_ERR(rtc->rtc)) {           // <<<< this needs to be earlier >>>>
           err = PTR_ERR(rtc->rtc);
           goto out_free_irq;
   }
   ..."

This patch moves setting the uie_unsupported flag to after we validate
the rtc->rtc pointer to resolve this.

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: Provide flag for rtc devices that don't support UIE

2012-03-16T01:23:10+00:00

Richard Weinberger noticed that on some RTC hardware that
doesn't support UIE mode, due to coarse granular alarms
(like 1minute resolution), the current virtualized RTC
support doesn't properly error out when UIE is enabled.

Instead the current code queues an alarm for the next second,
but it won't fire until up to a miniute later.

This patch provides a generic way to flag this sort of hardware
and fixes the issue on the mpc5121 where Richard noticed the
problem.

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.
