2014-10-20rtc: drop owner assignment from platform_driversWolfram Sang1-1/+0
A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
2013-05-18drivers/rtc: don't check resource with devm_ioremap_resourceWolfram Sang1-6/+0
devm_ioremap_resource does sanity checks on the given resource. No need to duplicate this in the driver. Signed-off-by: Wolfram Sang <wsa@the-dreams.de> Acked-by: Stephen Warren <swarren@nvidia.com>
2013-04-30drivers/rtc/rtc-tegra.c: use managed rtc_device_register()Laxman Dewangan1-23/+5
Use devm_rtc_device_register() for registering RTC device. This will reduce the code for unregistering RTC device in cleanup path and remove the implementation of remove callback of platform driver.

2013-04-30drivers/rtc/rtc-tegra.c: set irq name as device nameLaxman Dewangan1-1/+1
The irq name of tegra rtc shows as "rtc alarm" which actually does not reflect the name related to driver. Passing the device name to have the irq names with driver name.

2013-04-30drivers/rtc/rtc-tegra.c: use struct dev_pm_ops for power managementLaxman Dewangan1-10/+8
Make the Tegra RTC controller driver define its PM callbacks through a struct dev_pm_ops object rather than by using legacy PM hooks in struct platform_driver.

2013-04-30drivers/rtc/rtc-tegra.c: protect suspend/resume callbacks with CONFIG_PM_SLEEPLaxman Dewangan1-2/+2
CONFIG_PM doesn't actually enable any of the PM callbacks, it only allows to enable CONFIG_PM_SLEEP and CONFIG_PM_RUNTIME. This means if CONFIG_PM is used to protect system sleep callbacks then it may end up unreferenced if only runtime PM is enabled. Hence protecting sleep callbacks with CONFIG_PM_SLEEP.

2013-04-30rtc: rtc-tegra: add __init/__exit annotationJingoo Han1-3/+3
When platform_driver_probe() is used, bind/unbind via sysfs is disabled. Thus, __init/__exit annotations can be added to probe()/remove().

2013-01-22rtc: Convert to devm_ioremap_resource()Thierry Reding1-5/+3
Convert all uses of devm_request_and_ioremap() to the newly introduced devm_ioremap_resource() which provides more consistent error handling. devm_ioremap_resource() provides its own error messages so all explicit error messages can be removed from the failure code paths.

2013-01-05drivers/rtc/rtc-tegra.c: convert to DT driverJoseph Lo1-0/+7
After Kernel 3.7, the Tegra device will only support booting with DT. The legacy Tegra RTC platform driver will not work anymore. This patch converts the driver to support DT.

2013-01-04Drivers: rtc: remove __dev* attributes.Greg Kroah-Hartman1-3/+3
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.

2012-05-30drivers/rtc/rtc-tegra.c: clean up probe/remove routinesHannu Heikkinen1-37/+13
Use the devres managed resource functions in the probe routine. Also affects the remove routine where the previously used free and release functions are not needed. The devm_* functions eliminate the need for manual resource releasing and simplify error handling. Resources allocated by devm_* are freed automatically on driver detach.
