rtc: drop owner assignment from platform_drivers

2014-10-20T14:21:31Z

A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang

drivers/rtc/rtc-ds1302.c: handle write protection

2013-07-03T23:07:59Z

This chip has a control register and can prevent altering saved clock. Without this patch we could have: (arm)root@pac14:~# date Tue May 21 03:08:27 MSK 2013 (arm)root@pac14:~# /etc/init.d/hwclock.sh show Tue May 21 11:13:58 2013 -0.067322 seconds (arm)root@pac14:~# /etc/init.d/hwclock.sh stop [info] Saving the system clock. [info] Hardware Clock updated to Tue May 21 03:09:01 MSK 2013. (arm)root@pac14:~# /etc/init.d/hwclock.sh show Tue May 21 11:14:15 2013 -0.624272 seconds The patch enables write access to rtc before the driver tries to write time and re-disables when time data is written.

drivers/rtc/rtc-ds1302.c: remove empty function

2013-07-03T23:07:53Z

After the switch to devm_ functions and the removal of rtc_device_unregister(), the 'remove' function does not do anything. Delete it. Signed-off-by: Sachin Kamat Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

rtc: rtc-ds1302: remove unnecessary platform_set_drvdata()

2013-07-03T23:07:50Z

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. Signed-off-by: Jingoo Han Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

rtc: rtc-ds1302: use devm_rtc_device_register()

2013-04-30T01:28:29Z

devm_rtc_device_register() is device managed and makes cleanup paths simpler. Signed-off-by: Jingoo Han Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

rtc: rtc-ds1302: use module_platform_driver_probe()

2013-04-30T01:28:23Z

Use module_platform_driver_probe() macro which makes the code smaller and simpler. Signed-off-by: Jingoo Han Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

rtc: rtc-ds1302: add __exit annotation

2013-04-30T01:28:21Z

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 Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

Drivers: rtc: remove __dev* attributes.

2013-01-03T23:57:02Z

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.

sh: mach-snapgear: Kill off machtype, consolidate board def.

2010-10-29T10:06:53Z

Only the secureedge5410 was ever supported by this code, so make the board specification explicit rather than perpetuating a mach group. Signed-off-by: Paul Mundt

rtc-ds1302: add some abstraction for new platform support

2010-05-25T15:07:08Z

The current ds1302 driver (or at least the one that lives in /drivers/rtc) seems to be designed for memory mapped devices only. This make it quite hard to add support for GPIO-based implementations (as this is the case for the upcoming Arcom Vulcan). This patch moves the direct register access to inline functions with explicit names. Still not as good as a proper platform driver, but at least neater.
