2013-07-03rtc: rtc-davinci: remove unnecessary platform_set_drvdata()Jingoo Han1-9/+2
The driver core clears the driver data to NULL after device_release or on probe failure, since commit 0998d063100 ("device-core: Ensure drvdata = NULL when no driver is bound"). Thus, it is not needed to manually clear the device driver data to NULL.

2013-04-29rtc: rtc-davinci: use devm_rtc_device_register()Jingoo Han1-6/+2
devm_rtc_device_register() is device managed and makes cleanup paths simpler. Signed-off-by: Jingoo Han <[email protected]> Signed-off-by: Andrew Morton <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>

Use module_platform_driver_probe() macro which makes the code smaller and simpler. Signed-off-by: Jingoo Han <[email protected]> Signed-off-by: Andrew Morton <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>
2013-04-29rtc: rtc-davinci: add __exit annotationJingoo Han1-2/+2
When platform_driver_probe() is used, bind/unbind via sysfs is disabled. Thus, __init/__exit annotations can be added to probe()/remove(). Signed-off-by: Jingoo Han <[email protected]> Signed-off-by: Andrew Morton <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>

2013-01-03Drivers: rtc: remove __dev* attributes.Greg Kroah-Hartman1-2/+2
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.

Use devm_kzalloc() and remove the error path free and the unload free as devm functions take care of freeing resources.

2012-12-17rtc: rtc-davinci: return correct error code if rtc_device_register() failsDevendra Naga1-2/+3
rtc_device_register() returns a pointer containing error code in case of error. Use that in the error return.

2012-03-23drivers/rtc: remove IRQF_DISABLEDYong Zhang1-1/+1
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.

2011-05-06rtc: davinci: Initialize drvdata before registering deviceWolfram Sang1-2/+3
Commit f44f7f96a20 ("RTC: Initialize kernel state from RTC") uncovered an issue in a number of RTC drivers, where the drivers call rtc_device_register before initializing the device or platform drvdata. This frequently results in null pointer dereferences when the rtc_device_register immediately makes use of the rtc device, calling rtc_read_alarm. The solution is to ensure the drvdata is initialized prior to registering the rtc device.

2011-03-09RTC: Clean out UIE icotl implementationsJohn Stultz1-4/+0
With the generic RTC rework, the UIE mode irqs are handled in the generic layer, and only hardware specific ioctls get passed down to the rtc driver layer. So this patch removes the UIE mode ioctl handling in the rtc driver layer, which never get used.

2011-03-09RTC: Cleanup rtc_class_ops->irq_set_freq()John Stultz1-17/+0
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.

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.

This driver features: * Alarm support. * Periodic interrupt by using a timer include into the RTC module. * The update interrupt is not supported by this RTC module. This driver was tested on a DM365 EVM by using the rtc-test application from the Documentation/rtc.txt.
