rtc: vr41xx: Wire up alarm_irq_enable

2016-05-04T21:51:25+00:00

commit a25f4a95ec3cded34c1250364eba704c5e4fdac4 upstream.

drivers/rtc/rtc-vr41xx.c:229: warning: ‘vr41xx_rtc_alarm_irq_enable’ defined but not used

Apparently the conversion to alarm_irq_enable forgot to wire up the
callback.

rtc: hym8563: fix invalid year calculation

2016-05-04T21:51:25+00:00

commit d5861262210067fc01b2fb4f7af2fd85a3453f15 upstream.

Year field must be in BCD format, according to
hym8563 datasheet.

Due to the bug year 2016 became 2010.

drivers/rtc/rtc-isl12057.c: fix masking of register values

2015-01-16T14:59:29+00:00

commit 5945b2880363ed7648e62aabba770ec57ff2a316 upstream.

When Intersil ISL12057 support was added by commit 70e123373c05 ("rtc: Add
support for Intersil ISL12057 I2C RTC chip"), two masks for time registers
values imported from the device were either wrong or omitted, leading to
additional bits from those registers to impact read values:

 - mask for hour register value when reading it in AM/PM mode. As
   AM/PM mode is not the usual mode used by the driver, this error
   would only have an impact on an externally configured RTC hour
   later read by the driver.
 - mask for month value. The lack of masking would provide an
   erroneous value if century bit is set.

This patch fixes those two masks.

drivers/rtc/rtc-sirfsoc.c: move hardware initilization earlier in probe

2015-01-16T14:59:29+00:00

commit 0e95325525c4383565cea4f402f15a3113162d05 upstream.

Move rtc register to be later than hardware initialization.  The reason
is that devm_rtc_device_register() will do read_time() which is a
callback accessing hardware.  This sometimes causes a hang in the
hardware related callback.

drivers/rtc/rtc-puv3.c: use dev_dbg() instead of dev_debug() for typo issue

commit c863810cefc7ffd782e5648a21bfb36a32c8b081 upstream.

rtc: rtc-at91rm9200: fix infinite wait for ACKUPD irq

2014-06-26T19:15:37+00:00

commit 2fe121e1f5aa3bf31b418a9790db6c400e922291 upstream.

The rtc user must wait at least 1 sec between each time/calandar update
(see atmel's datasheet chapter "Updating Time/Calendar").

Use the 1Hz interrupt to update the at91_rtc_upd_rdy flag and wait for
the at91_rtc_wait_upd_rdy event if the rtc is not ready.

This patch fixes a deadlock in an uninterruptible wait when the RTC is
updated more than once every second.  AFAICT the bug is here from the
beginning, but I think we should at least backport this fix to 3.10 and
the following longterm and stable releases.

drivers/rtc/rtc-hym8563.c: set uie_unsupported

2014-06-07T17:28:10+00:00

commit 282cba6b00a95f0277ed71551e3f6b0477e8836b upstream.

The alarm of the hym8563 only supports a minute accuracy, while the uie
wants an alarm one second in the future.  Therefore things like the
select() syscall will fail with a timeout, because the next alarm will
happen in a worst case of 60 seconds.

drivers/rtc/rtc-s3c.c: fix incorrect way of save/restore of S3C2410_TICNT for TYPE_S3C64XX

2014-03-04T15:55:48+00:00

On exynos5250, exynos5420 and exynos5260 it was observed that, after 1
cycle of S2R, the rtc-tick occurs at a very fast rate as compared to the
rtc-tick occuring before S2R.

This patch fixes the above issue by correcting the wrong way of
save/restore of S3C2410_TICNT for TYPE_S3C64XX.
