 ("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 seconds

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 automatically

Root-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
  regmap

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

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.

With the recent pinctrl-single changes, SoCs such as Texas
Instrument's OMAP processors can treat wake-up events from deeper idle
states as interrupts.

Let's add support for the optional second interrupt for wake-up using
the generic wakeirq support added in commit 4990d4fe ("PM /
Wakeirq: Add automated device wake IRQ handling")

Finally, to pass the wake-up interrupt in the dts file,
interrupts-extended property needs to be passed.

This is similar in approach to commit 2a0b965c ("serial: omap: Add
support for optional wake-up") + ee83bd3b

 ("serial: omap: Switch

Pull dmaengine updates from Vinod Koul:
 "This time we have aded a new capability for scatter-gathered memset
  using dmaengine APIs.  This is supported in xdmac & hdmac drivers

  We have added support for reusing descriptors for examples like video
  buffers etc.  Driver will follow

  The behaviour of descriptor ack has been clarified and documented

  New devices added are:
   - dma controller in sun[457]i SoCs
   - lpc18xx dmamux
   - ZTE ZX296702 dma controller
   - Analog Devices AXI-DMAC DMA controller
   - eDMA support for dma-crossbar
   - imx6sx support in imx-sdma driver
   - imx-sdma device to device support

  Other:
   - jz4780 fixes
   - ioatdma large refactor and cleanup for removal of ioat v1 and v2
     which is deprecated and fixes
   - ACPI support in X-Gene DMA engine driver
   - ipu irq fixes
   - mvxor fixes
   - minor fixes spread thru drivers"

[ The Kconfig and Makefile entries got re-sorted alphabetically, and I
  handled the conflict with the new Intel integrated IDMA driver by
  slightly mis-sorting it on purpose: "IDMA64" got sorted after "IMX" in
  order to keep the Intel entries together.  I think it might be a good
  idea to just rename the IDMA64 config entry to INTEL_IDMA64 to make
  the sorting be a true sort, not this mismash.

  Also, this merge disables the COMPILE_TEST for the sun4i DMA
  controller, because it does not compile cleanly at all.     - Linus ]

Pull pin control updates from Linus Walleij:
 "This is the bulk of pin control changes for the v4.3 development
  cycle.

  Like with GPIO it's a lot of stuff.  If my subsystems are any sign of
  the overall tempo of the kernel v4.3 will be a gigantic diff.

[ It looks like 4.3 is calmer than 4.2 in most other subsystems, but
  we'll see - Linus ]

  Core changes:

   - It is possible configure groups in debugfs.

   - Consolidation of chained IRQ handler install/remove replacing all
     call sites where irq_set_handler_data() and
     irq_set_chained_handler() were done in succession with a combined
     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"

Pull GPIO updates from Linus Walleij:
 "This is the bulk of GPIO changes for the v4.3 kernel cycle.

  There is quite a lot going on in the GPIO subsystem this merge window,
  so the main matter is decribed below.

  The hits in other subsystems when making the GPIO flags optional are
  all ACKed by their respective subsystem maintainers.

  Core changes:

   - Root out the wrapper devm_gpiod_get() and gpiod_get() etc versions
     of the descriptor calls that did not use the flags argument on the
     end.  This was around for too long and eventually Uwe Kleine-König
     took the time to clean it out and the last users are removed along
     with the macros in this tag.  In several cases the use of flags
     simplifies the code.  For this reason we have (ACKed) patches
     hitting in DRM, IIO, media, NFC, USB+PHY up until we hammer in the
     nail with removing the macros.

   - Add a fat document describing how much ready-made GPIO stuff we
     have i the kernel to discourage people from reinventing a square
     wheel in userspace, as so often happens.

   - Create a separate lockdep class for each instance of a GPIO IRQ
     chip instead of using one class for all chips, as the current code
     will not work with systems with several GPIO chips doing lockdep
     debugging.

   - Protect against driver unloading also when a GPIO line is only used
     as IRQ for the GPIOLIB_IRQCHIP helpers.

   - If the GPIO chip has no designated owner, assign the parent device
     driver owner as owner.

   - Consolidation of chained IRQ handler install/remove replacing all
     call sites where irq_set_handler_data() and
     irq_set_chained_handler() were done in succession with a combined
     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 and Jiang Liu 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.

   - Rob Herring killed off the set_irq_flags() for all GPIO drivers.
     This was an ARM specific function that is replaced with the generic
     irq_modify_status() where special flags are actually needed.

   - When an OF node has a pin range for its GPIOs, return -EPROBE_DEFER
     if the pin controller isn't available.  Pretty logical, yet needed
     to be fixed.

   - If a driver using GPIOLIB_IRQCHIP has its own irq_*_resources call
     back, then call these instead of the defaults provided by the
     GPIOLIB.

   - Fix an undocumented ABI hole: named GPIOs were not properly
     documented.

  Driver improvements:

   - Add get_direction() support to the generic GPIO driver, it's
     strange that we didn't have that before.

   - Make it possible to have input-only GPIO chips using the generic
     GPIO driver.

   - Clean out platform data support from the Emma Mobile (EM) driver

   - Finegrained runtime PM support for the RCAR driver.

   - Support r8a7795 (R-car H3) in the RCAR driver.

   - Support interrupts on GPIOs 16 thru 31 in the DaVinci driver.

   - Some consolidation and new support in the MPC8xxx driver, we now
     support MPC5125.

   - Preempt-RT-friendly patches: the OMAP, MPC8xxx, drivers uses raw
     spinlocks making it work better with the realime patches.

   - Interrupt support for the EXTRAXFS GPIO driver.

   - Make the ETRAXFS GPIO driver support also ARTPEC-3.

   - Interrupt and wakeup support for the BRCMSTB driver, also for
     wakeup from S5 cold boot.

   - Mask MXC IRQs during suspend.

   - Improve OMAP2 GPIO set_debounce() to work according to spec.

   - The VF610 driver handles IRQs properly.

  New drivers:

   - ZTE ZX GPIO driver"
