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.

commit 7ecd9a3f062147400e605713724dd67dbb7e5053 upstream.
The platform device must be registered as wakeup capable before
registering the class device, or the wakealarm attribute will not be
created.Also make sure to unregister the wakeup source on probe errors.

commit 44c63a570aaec3c5d5569d63b7c4a31ddd88cae0 upstream.
This series fixes a few issues with the omap rtc-driver, cleans up a
bit, adds device abstraction, and finally adds support for the PMIC
control feature found in some revisions of this RTC IP block.Ultimately, this allows for powering off the Beaglebone and waking it up
again on RTC alarms.This patch (of 20):
Make sure not to reset the clock-source configuration when enabling the
32kHz clock mux.Until the clock source can be configured through device tree we must not
overwrite settings made by the bootloader (e.g. clock-source
selection).Fixes: cd914bba03d8 ("drivers/rtc/rtc-omap.c: add support for enabling 32khz clock")

only check for negative values, so a possible positive value does not
get detected if the compiler chooses not to inline the entire call

The max77686 mfd driver adds a regmap IRQ chip which creates an IRQ
domain that is used to map the virtual RTC alarm1 interrupt.The RTC driver assumes that this will always be true since the PMIC IRQ
is a required property according to the max77686 DT binding doc. If an
"interrupts" property is not defined for a max77686 PMIC, then the mfd
probe function will fail and the RTC platform driver will never be
probed.But even when it is not possible to probe the rtc-max77686 driver
without a regmap IRQ chip, it's better to explicitly check if the IRQ
chip data is not NULL and gracefully fail instead of getting an OOPS.Signed-off-by: Javier Martinez Canillas

The MAX77686 RTC chip has two features called SMPL (Sudden Momentary
Power Loss) and WTSR (Watchdog Timeout and Software Resets). Support
for these features seems to be implemented in the driver but compilation
is disabled using a C pre-processor conditional.This code has been disabled since the driver was original merged in
commit fca1dd031a28 ("rtc: max77686: add Maxim 77686 driver").So, since this code has never been built, let's just remove it.

This series add support for the Real Time clock present in the Maxim 77802
Power Managment IC. The version number is quite high because it
previously was part of a bigger series [0] that aimed to add support for
all the devices in the max77802 PMIC. But now that the max77802
dependencies were already merged for 3.17, the series were split but I
kept the version numbering.While working on the max77802 rtc support a lot of feedback was given and
the issues pointed out also apply to a driver for a similar PMIC RTC
(max77686). So patches 01/06 to 05/06 in the series are cleanups for the
max77686 driver and patch 06/06 adds the support for the max77802 RTC.The series were tested on an Exynos5250 Snow (max77686) and
Exynos5420 Peach Pit (max77802) machines.This patch (of 6):
The max77686 includes an RTC that keeps power during suspend. It's
convenient to be able to use it as a wakeup source.Signed-off-by: Doug Anderson

careful not to enable the EFI rtc driver due to the generally buggy

on 32-bit tablets,https://bugzilla.kernel.org/show_bug.cgi?id=84241#c21

This patch introduces the driver for the RTC in the Allwinner A31 and
A23 SoCs.Unlike the RTC found in A10/A20 SoCs, which was part of the timer, the
RTC in A31/A23 are a separate hardware block, which also contain a few
controls for the RTC block hardware (a regulator and RTC block GPIO pin
latches), while also having separate interrupts for the alarms.The hardware is different enough to make a different driver for it.

The rtc-s5m driver used to support devices without irq specified in the
past. Re-add this support.The patch fixes boot for Insignal's Exynos4412 based Origen board.
