2009-06-20rtc: make rtc_update_irq callable with irqs enabledAtsushi Nemoto1-2/+0
The rtc_update_irq() might be called with irqs enabled, if a interrupt handler was registered without IRQF_DISABLED. Use spin_lock_irqsave/spin_unlock_irqrestore instead of spin_lock/spin_unlock. Also update kerneldoc and drivers which do extra work to follow the current interface spec, as suggestted by David Brownell.

2009-01-07rtc: use set_mmss when set_time is not availableAlessandro Zummo1-7/+1
Drivers should only need to implement either set_mmss (counter based RTCs) or set_time (most RTCs). The RTC subsystem will handle them appropriately.

2008-04-28rtc: silence section mismatch warning in rtc-testSam Ravnborg1-4/+4
Fix following warning: WARNING: vmlinux.o(.data+0x253e28): Section mismatch in reference from the variable test_drv to the function .devexit.text:test_remove() Fix by renaming the platfrom_driver variable from *_drv to *_driver so modpost ignore the reference to an __devexit section.

2007-05-08rtc: rtc interfaces don't use class_deviceDavid Brownell1-3/+3
This patch removes class_device from the programming interface that the RTC framework exposes to the rest of the kernel. Now an rtc_device is passed, which is more type-safe and streamlines all the relevant code.

2006-11-26[PATCH] rtc class locking bugfixesDavid Brownell1-0/+2
I got a lockdep warning when running "rtctest" so I though it'd be good to see what was up. - The warning was for rtc->irq_task_lock, gotten from rtc_update_irq() by irq handlerss ... but in a handful of other cases, grabbed without blocking IRQs. - Some callers to rtc_update_irq() were not ensuring IRQs were blocked, yet the routine expects that; make sure all callers block IRQs. It would appear that RTC API tests haven't been part of anyone's kernel regression test suite recently, at least not with lockdep running.

2006-10-01[PATCH] constify rtc_class_ops: update driversDavid Brownell1-1/+1
Update RTC framework so that drivers can constify their method tables, moving them from ".data" to ".rodata". Then update the drivers.

2006-05-21[PATCH] rtc subsystem: use ENOIOCTLCMD and ENOTTY where appropriateAlessandro Zummo1-1/+1
Appropriately use -ENOIOCTLCMD and -ENOTTY when the ioctl is not implemented by a driver. (akpm: we're not allowed to return -ENOIOCTLCMD to userspace. This patch does the right thing).

2006-04-11[PATCH] RTC subsystem: fix proc outputAlessandro Zummo1-1/+0
Move the "24hr: yes" proc output from drivers to rtc proc code. This is required because the time value in the proc output is always in 24hr mode regardless of the driver.
