drivers/rtc/class: convert from Legacy pm ops to dev_pm_ops

2013-07-03T23:08:00Z

Convert drivers/rtc/class to use dev_pm_ops for power management and remove Legacy PM ops hooks. With this change, rtc class registers suspend/resume callbacks via class->pm (dev_pm_ops) instead of Legacy class->suspend/resume. When __device_suspend() runs call-backs, it will find class->pm ops for the rtc class.

drivers/rtc/class.c: use struct device as the first argument for devm_rtc_device_register()

2013-04-30T01:28:22Z

Other devm_* APIs use 'struct device *dev' as the first argument. Thus, in order to sync with other devm_* functions, struct device is used as the first argument for devm_rtc_device_register().

rtc: add devm_rtc_device_{register,unregister}()

2013-04-30T01:28:21Z

These functions allow the driver core to automatically clean up any allocation made by rtc drivers. Thus it simplifies the error paths. Signed-off-by: Jingoo Han Acked-by: Tejun Heo Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

rtc: Skip the suspend/resume handling if persistent clock exist

2013-01-16T02:16:08Z

All the RTC suspend and resume functions are to compensate the sleep time, but this is already done in timekeeping.c if persistent clock exist. Cc: Thomas Gleixner Cc: John Stultz Cc: Alessandro Zummo Cc: Arve Hjønnevåg Signed-off-by: Feng Tang Signed-off-by: John Stultz

revert "rtc: recycle id when unloading a rtc driver"

2012-12-21T01:40:20Z

Revert commit 2830a6d20139df2198d63235df7957712adb28e5. We already perform the ida_simple_remove() in rtc_device_release(), which is an appropriate place. Commit 2830a6d20 ("rtc: recycle id when unloading a rtc driver") caused the kernel to emit ida_remove called for id=0 which is not allocated. warnings when rtc_device_release() tries to release an alread-released ID. Let's restore things to their previous state and then work out why Vincent's kernel wasn't calling rtc_device_release() - presumably a bug in a specific sub-driver.

rtc_sysfs_show_hctosys(): display 0 if resume failed

2012-10-05T18:05:04Z

Without this patch /sys/class/rtc/$CONFIG_RTC_HCTOSYS_DEVICE/hctosys contains a 1 (meaning "This rtc was used to initialize the system clock") even if setting the time by do_settimeofday() at bootup failed. The RTC can also be used to set the clock on resume, if it did 1, otherwise 0. Previously there was no indication if the RTC was used to set the clock in resume. This uses only CONFIG_RTC_HCTOSYS_DEVICE for conditional compilation instead of it and CONFIG_RTC_HCTOSYS to be more consistent. rtc_hctosys_ret was moved to class.c so class.c no longer depends on hctosys.c.

rtc: recycle id when unloading a rtc driver

2012-10-05T18:05:02Z

When calling rtc_device_unregister, we are not freeing the id used by the driver. So when doing a unload/load cycle for a RTC driver (e.g. rmmod rtc_cmos && modprobe rtc_cmos), its id is incremented by one. As a consequence, we no longer have neither an rtc0 driver nor a /proc/driver/rtc (as it only exists for the first driver).
