Commit d5a1c7e3fc38 ("rtc-cmos: Add an alarm disable quirk") that
added a special quirk is not needed because [PATCH 1/2] of this
patchset makes the kernel more robust:
rtc-cmos: Cancel alarm timer if alarm time is equal to now+1 secondsSigned-off-by: Adrian Huang

Signed-off-by: Alexandre Belloni -
Steps to reproduce the problem:
1) Enable RTC wake-up option in BIOS Setup
2) Issue one of these commands in the OS: "poweroff"
or "shutdown -h now"
3) System will shut down and then reboot automaticallyRoot-cause of the issue:
1) During the shutdown process, the hwclock utility is used
to save the system clock to hardware clock (RTC).
2) The hwclock utility invokes ioctl() with RTC_UIE_ON. The
kernel configures the RTC alarm for the periodic interrupt
(every 1 second).
3) The hwclock uitlity closes the /dev/rtc0 device, and the
kernel disables the RTC alarm irq (AIE bit of Register B)
via ioctl() with RTC_UIE_OFF. But, the configured alarm
time is the current_time + 1.
4) After the next 1 second is elapsed, the AF (alarm
interrupt flag) of Register C is set.
5) The S5 handler in BIOS is invoked to configure alarm
registers (enable AIE bit and configure alarm date/time).
But, BIOS does not clear the previous interrupt status
during alarm configuration. Therefore, "AF=AIE=1" causes
the rtc device to trigger an interrupt.
6) So, the machine reboots automatically right after shutdown.This patch cancels the alarm timer if the following condictions are
met (suggested by Alexandre):
1) The configured alarm time is equal to current_time + 1
seconds.
2) The AIE timer is not in use.The member 'alarm_expires' is introduced in struct cmos_rtc because
of the following reasons:
1) The configured alarm time can be retrieved from
cmos_read_alarm(), but we need to take the 'wrapped
timestamp' and 'time rollover' into consideration. The
function __rtc_read_alarm() eliminates the concerns. To
avoid the duplicated code in the lower level RTC driver,
invoking __rtc_read_alarm from the lower level RTC driver
is not encouraged. Moreover, the compilation error 'the
undefined __rtc_read_alarm" is observed if the lower level
RTC driver is compiled as a kernel module.
2) The uie_rtctimer.node.expires and aie_timer.node.expires can
be retrieved for the configured alarm time. But, the problem
is that either of them might configure the CMOS alarm time.
We cannot make sure UIE timer or AIE tiemr configured the
CMOS alarm time before. (uie_rtctimer or aie_timer is enabled
and then is disabled).
3) The patch introduces the member 'alarm_expires' to keep the
newly configured alarm time, so the above-mentioned concerns
can be eliminated.The issue goes away after 20-time shutdown tests.

Add DA9062 RTC support into the existing DA9063 RTC driver component by
using generic access tables for common register and bit mask definitions.The following change will add generic register and bit mask support to the
DA9063 RTC. The changes are slightly complicated by requiring support for
three register sets: DA9063-AD, DA9063-BB and DA9062-AA.The following alterations have been made to the DA9063 RTC:
- Addition of a da9063_compatible_rtc_regmap structure to hold all generic
registers and bitmasks for this type of RTC component.
- A re-write of struct da9063 to use pointers for regmap and compatible
registers/masks definitions
- Addition of a of_device_id table for DA9063 and DA9062 defaults
- Refactoring functions to use struct da9063_compatible_rtc accesses to
generic registers/masks instead of using defines from registers.h
- Re-work of da9063_rtc_probe() to use of_match_node() and dev_get_regmap()
to provide initialisation of generic registers and masks and access to

Instead of creating wakealarm attribute manually, after the device has been
registered, let's rely on facilities provided by the attribute groups to
control which attributes are visible and which are not. This allows to
create all needed attributes at once, at the same time that we register RTC

rtc-opal driver provides support for rtc alarms via
timed-power-on(tpo). However some Power platforms like BML use a fake
rtc clock and don't support tpo. Such platforms are indicated by the
missing 'has-tpo' property in the device tree.Current implementation however enables callback for
rtc_class_ops.read/set alarm irrespective of the tpo support from the
platform. This results in a failed opal call when kernel tries to read
an existing alarms via opal_get_tpo_time during rtc device registration.This patch fixes this issue by setting opal_rtc_ops.read/set_alarm
callback pointers only when tpo is supported.Acked-by: Michael Neuling

interrupts-extended property needs to be passed.This is similar in approach to commit 2a0b965cfb6e ("serial: omap: Add

call to irq_set_chained_handler_and_data(). This series was
created by Thomas Gleixner after the problem was observed by
Russell King.- Tglx also made another series of patches switching
__irq_set_handler_locked() for irq_set_handler_locked() which is
way cleaner.- Tglx also wrote a good bunch of patches to make use of
irq_desc_get_xxx() accessors and avoid looking up irq_descs from
IRQ numbers. The goal is to get rid of the irq number from the
handlers in the IRQ flow which is nice.Driver feature enhancements:
- Power management support for the SiRF SoC Atlas 7.
- Power down support for the Qualcomm driver.
- Intel Cherryview and Baytrail: switch drivers to use raw spinlocks
in IRQ handlers to play nice with the realtime patch set.- Rework and new modes handling for Qualcomm SPMI-MPP.
- Pinconf power source config for SH PFC.
New drivers and subdrivers:
- A new driver for Conexant Digicolor CX92755.
- A new driver for UniPhier PH1-LD4, PH1-Pro4, PH1-sLD8, PH1-Pro5,
ProXtream2 and PH1-LD6b SoC pin control support.- Reverse-egineered the S/PDIF settings for the Allwinner sun4i
driver.- Support for Qualcomm Technologies QDF2xxx ARM64 SoCs
- A new Freescale i.mx6ul subdriver.
Cleanup:
- Remove platform data support in a number of SH PFC subdrivers"
