rtc: drop owner assignment from platform_drivers

2014-10-20T14:21:31+00:00

A platform_driver does not need to set an owner, it will be populated by the
driver core.

RTC drivers must not return an error after device registration.  This
patch makes RTC registration as the last action.

rtc: mc13xxx: make rtc_read_time() more readable

2014-04-03T23:21:21+00:00

Remove unnecessary locks when reading the time and make the read
operation until the values of day matched between reading the seconds,
it will make the mc13xxx_rtc_read_time() procedure more readable.
Additionally, patch introduced a "seconds in a day" definition.

rtc: mc13xxx: change RTC validation scheme

2014-04-03T23:21:21+00:00

Datasheet says: "When the VSRTC voltage drops to the range of 0.9 - 0.8V,
the RTCPORB reset signal is generated and the contents of the RTC will
be reset.  .  To inform the processor that the contents of the RTC
are no longer valid due to the reset, a timer reset interrupt function
is implemented with the RTCRSTI bit." This patch makes the RTC valid by
default until RTCRST interrupt occurs.

rtc: mc13xxx: request IRQs after RTC registration

2014-04-03T23:21:20+00:00

Interrupts can appear after request_irq and interrupt handlers can use
the RTC device, but currently we register RTC after IRQs.  This patch
changes this order and simplify error path a bit.

rtc: mc13xxx: remove __exit_p()

2014-04-03T23:21:20+00:00

Since we no longer allow building without hotplug, the
mc13xxx_rtc_remove() function is always present and we should not use
__exit_p() to refer to it.

rtc: rtc-mc13xxx: remove unnecessary platform_set_drvdata()

2013-07-03T23:07:51+00:00

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.
