rtc: rtc-spear: convert spear_rtc_driver to dev_pm_ops

2013-04-30T01:28:39Z

Instead of using legacy suspend/resume methods, using newer dev_pm_ops structure allows better control over power management. Signed-off-by: Jingoo Han Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

rtc: rtc-spear: use devm_rtc_device_register()

2013-04-30T01:28:27Z

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

rtc: Convert to devm_ioremap_resource()

2013-01-22T19:41:57Z

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.

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.

rtc: rtc-spear: Provide flag for no support of UIE mode

2012-12-18T01:15:21Z

The applications can set the RTC hardware to trigger interrupts in one of three modes: * AIE: Alarm interrupt * UIE: Update interrupt (ie: once per second) * PIE: Periodic interrupt (sub-second irqs) The above defined 3 modes are to be supported in the RTC HW in form of interrupts. The SPEAr RTC hardware does not support the later two modes. There have been refinements in the RTC core in mainline related to use of timer queue infrastructure to manage events in RTC. Please refer the below mentioned patch for details: * RTC: Rework RTC code to use timerqueue for events * SHA ID: 6610e0893b8bc6f59b14fed7f089c5997f035f88 There have been provisions added to support hardware that do not have support the UIE mode. Please refer the following patch. * rtc: Provide flag for rtc devices that don't support UIE * SHA ID: 4a649903f91232d02284d53724b0a45728111767 The patch makes use of the provision defined in the above patch to update the hardware status of UIE mode.

rtc: rtc-spear: Add clk_{un}prepare() support

2012-12-18T01:15:20Z

clk_{un}prepare is mandatory for platforms using common clock framework. Because for SPEAr we don't do anything in clk_{un}prepare() calls, just call them once in probe/remove.

rtc: rtc-spear: use devm_*() routines

2012-12-18T01:15:20Z

Free the rtc-spear driver from tension of freeing resources :) devm_* derivatives of multiple routines are used while allocating resources, which would be freed automatically by kernel.

drivers/rtc/rtc-spear.c: fix several error checks

2012-10-05T18:05:03Z

There are several comparisons of a unsigned int to less than zero int spear RTC driver. Such a check will always be true. In all these cases a signed int is assigned to the unsigned variable, which is checked, before. So the right fix is to make the checked variable signed as well. In one case the check can be dropped completely, because all it does it returns 'err' if 'err' is less than zero, otherwise it returns 0. Since in this particular case 'err' is always either 0 or less this is the same as just returning 'err'. The issue has been found using the following coccinelle semantic patch: // @@ type T; unsigned T i; @@ ( *i < 0 | *i >= 0 ) // Signed-off-by: Lars-Peter Clausen Cc: Viresh Kumar Cc: Alessandro Zummo Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

rtc/spear: add Device Tree probing capability

2012-05-29T23:22:33Z

SPEAr platforms now support DT and so must convert all drivers support DT. This patch adds DT probing support for rtc and updates its documentation too.
