5593ce64d8 irqchip: renesas-irqc: Add functional clock to bindings 
The external IRQ controller has a functional clock, which is used for
power management. Document it.

Fix a typo in the r8a73a4 SoC name while we're at it.

a135c717d5 Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus 
Pull MIPS updates from Ralf Baechle:
 "This is the main pull request for MIPS:

   - a number of fixes that didn't make the 3.19 release.

   - a number of cleanups.

   - preliminary support for Cavium's Octeon 3 SOCs which feature up to
     48 MIPS64 R3 cores with FPU and hardware virtualization.

   - support for MIPS R6 processors.

     Revision 6 of the MIPS architecture is a major revision of the MIPS
     architecture which does away with many of original sins of the
     architecture such as branch delay slots.  This and other changes in
     R6 require major changes throughout the entire MIPS core
     architecture code and make up for the lion share of this pull
     request.

   - finally some preparatory work for eXtendend Physical Address
     support, which allows support of up to 40 bit of physical address
     space on 32 bit processors"

     [ Ahh, MIPS can't leave the PAE brain damage alone.  It's like
       every CPU architect has to make that mistake, but pee in the snow
       by changing the TLA.  But whether it's called PAE, LPAE or XPA,
       it's horrid crud   - Linus ]

18a8d49973 The clock framework changes for 3.20 contain the usual driver additions, 
enhancements and fixes mostly for ARM32, ARM64, MIPS and Power-based
 devices. Additionaly the framework core underwent a bit of surgery with
 two major changes. The boundary between the clock core and clock
 providers (e.g clock drivers) is now more well defined with dedicated
 provider helper functions. struct clk no longer maps 1:1 with the
 hardware clock but is a true per-user cookie which helps us tracker
 users of hardware clocks and debug bad behavior. The second major change
 is the addition of rate constraints for clocks. Rate ranges are now
 supported which are analogous to the voltage ranges in the regulator
 framework. Unfortunately these changes to the core created some
 breakeage. We think we fixed it all up but for this reason there are
 lots of last minute commits trying to undo the damage.

On some chips, like the TPS386000, the trigger cannot be disabled
and the CPU must keep toggling the line at all times. Add a switch
"always_running" to keep toggling the GPIO line regardless of the
state of the soft part of the watchdog. The "armed" member keeps
track of whether a timeout must also cause a reset.

878ba61aa9 ARM: SoC platform changes 
New and updated SoC support. Also included are some cleanups where the
 platform maintainers hadn't separated cleanups from new developent in
 separate branches.
 
 Some of the larger things worth pointing out:
 
 - A large set of changes from Alexandre Belloni and Nicolas Ferre
   preparing at91 platforms for multiplatform and cleaning up quite a
   bit in the process.
 - Removal of CSR's "Marco" SoC platform that never made it out to the
   market. We love seeing these since it means the vendor published
   support before product was out, which is exactly what we want!
 
 New platforms this release are:
 
 - Conexant Digicolor (CX92755 SoC)
 - Hisilicon HiP01 SoC
 - CSR/sirf Atlas7 SoC
 - ST STiH418 SoC
 - Common code changes for Nvidia Tegra132 (64-bit SoC)
 
 We're seeing more and more platforms having a harder time labelling
 changes as cleanups vs new development -- which is a good sign that
 we've come quite far on the cleanup effort. So over time we might start
 combining the cleanup and new-development branches more.

Merge tag 'soc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC platform changes from Olof Johansson:
 "New and updated SoC support.  Also included are some cleanups where
  the platform maintainers hadn't separated cleanups from new developent
  in separate branches.

  Some of the larger things worth pointing out:

   - A large set of changes from Alexandre Belloni and Nicolas Ferre
     preparing at91 platforms for multiplatform and cleaning up quite a
     bit in the process.

   - Removal of CSR's "Marco" SoC platform that never made it out to the
     market.  We love seeing these since it means the vendor published
     support before product was out, which is exactly what we want!

  New platforms this release are:

   - Conexant Digicolor (CX92755 SoC)
   - Hisilicon HiP01 SoC
   - CSR/sirf Atlas7 SoC
   - ST STiH418 SoC
   - Common code changes for Nvidia Tegra132 (64-bit SoC)

  We're seeing more and more platforms having a harder time labelling
  changes as cleanups vs new development -- which is a good sign that
  we've come quite far on the cleanup effort.  So over time we might
  start combining the cleanup and new-development branches more"

This patch adds support for Abracon AB-RTCMC-32.768kHz-B5ZE-S3
RTC/Calendar module w/ I2C interface.

This support includes RTC time reading and setting, Alarm (1 minute
accuracy) reading and setting, and battery low detection.  The device also
supports frequency adjustment and two timers but those features are
currently not implemented in this driver.  Due to alarm accuracy
limitation (and current lack of timer support in the driver), UIE mode is
not supported.

446810f2dd of: add vendor prefix for Abracon Corporation 
This series adds support for Abracon AB-RTCMC-32.768kHz-B5ZE-S3 I2C RTC
chip. Unlike many RTC chips, it includes an internal oscillator which
spares room on the PCB. It also has some interesting features, like
battery low detection (which the driver in this series supports). The
only small "limitation" (mainly due to what RTC subsystem expects from
RTC chips) is the fact that its alarm is accurate to the second. This
series provides a solution (described below) for that limitation using
another mechanism of the chip.

I decided to split support between three different patches for
this v0:

- Patch 1/3: it simply references Abracon Corporation in vendor-prefixes
  documentation file. As Abracon has no NASDAQ ticker symbol; I have
  decided to use "abcn" (I initially started my work w/ "ab" but later
  changed for "abcn" which looked more meaningful)
- Patch 2/3: it adds initial support for the chip and provides the
  ability to read/write time and also read/write alarm. As the alarm
  the chip provides is accurate to the minute, the support provided
  by this patch also has this limitation (e.g. UIE mode is not
  supported).
- Patch 3/3: the chip supports a watchdog timer which can be used to
  extend the alarm mechanism in patch 2/3 in order to provide support
  for alarms under one minute (e.g. support UIE mode). In practice,
  the logic I implemented is to use the watchdog timer for alarms which
  are at most 4 minutes in the future and use the common alarm mechanism
  for alarms which are set to larger values. With that additional patch
  the device fully passes the rtctest.c program.

I decided to split the driver between two patches (2 and 3 of 3) in
order to ease review: patch 2 should be pretty straightforward to read
for someone familiar w/ RTC subsystem. Patch 3 only extends what is in
patch 2 regarding alarms.

This patch (of 3):

298ff0122a rtc: rtc-isl12057: add isil,irq2-can-wakeup-machine property for in-tree users 
Current in-tree users of ISL12057 RTC chip (NETGEAR ReadyNAS 102, 104 and
2120) do not have the IRQ#2 pin of the chip (associated w/ the Alarm1
mechanism) connected to their SoC, but to a PMIC (TPS65251 FWIW).  This
specific hardware configuration allows the NAS to wake up when the alarms
rings.

Recently introduced alarm support for ISL12057 relies on the provision of
an "interrupts" property in system .dts file, which previous three users
will never get.  For that reason, alarm support on those devices is not
function.  To support this use case, this patch adds a new DT property for
ISL12057 (isil,irq2-can-wakeup-machine) to indicate that the chip is
capable of waking up the device using its IRQ#2 pin (even though it does
not have its IRQ#2 pin connected directly to the SoC).

This specific configuration was tested on a ReadyNAS 102 by setting an
alarm, powering off the device and see it reboot as expected when the
alarm rang w/:

  # echo `date '+%s' -d '+ 1 minutes'` > /sys/class/rtc/rtc0/wakealarm
  # shutdown -h now

As a side note, the ISL12057 remains in the list of trivial devices,
because the property is not per se required by the device to work but can
help handle system w/ specific requirements.  In exchange, the new feature
is described in details in a specific documentation file.

   - Add support for the A31S variant in the sun6i driver.
   - EMEv2 support in the Renesas PFC driver.
   - Ass support for Qualcomm MSM8916 in the qcom driver.
 
 - Deleted features

Merge tag 'pinctrl-v3.20-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pincontrol updates from Linus Walleij:
 :This is the bulk of pin control changes for the v3.20 cycle:

  Framework changes and enhancements:
   - Passing -DDEBUG recursively to subdir drivers so we get debug
     messages properly turned on.
   - Infer map type from DT property in the groups parsing code in the
     generic pinconfig code.
   - Support for custom parameter passing in generic pin config.  This
     is used when you are using the generic pin config, but want to add
     a few custom properties that no other driver will use.

  New drivers:
   - Driver for the Xilinx Zynq
   - Driver for the AmLogic Meson SoCs

  New features in drivers:
   - Sleep support (suspend/resume) for the Cherryview driver
   - mvebeu a38x can now mux a UART on pins MPP19 and MPP20
   - Migrated the qualcomm driver to generic pin config handling of
     extended config options in the core code.
   - Support BUS1 and AUDIO in the Exynos pin controller.
   - Add some missing functions in the sun6i driver.
   - Add support for the A31S variant in the sun6i driver.
   - EMEv2 support in the Renesas PFC driver.
   - Add support for Qualcomm MSM8916 in the qcom driver.

  Deleted features
   - Drop support for the SiRF Marco that was never released to the
     market.
   - Drop SH7372 support as the support for this platform is removed
     from the kernel"
