Linus Torvalds b2e3c4319d ARM: SoC driver updates 
Driver updates for ARM SoCs.
 
 A handful of driver changes this time around. The larger changes are:
 
  - Reset drivers for hi3660 and zx2967
  - AHCI driver for Davinci, acked by Tejun and brought in here due to
    platform dependencies
  - Cleanups of atmel-ebi (External Bus Interface)
  - Tweaks for Rockchip GRF (General Register File) usage (kitchensink misc
    register range on the SoCs)
  - PM domains changes for support of two new ZTE SoCs (zx296718 and zx2967)

Marek Szyprowski b13b2330aa soc: samsung: pm_domains: Read domain name from the new label property 
Device tree nodes for each power domain should use generic "power-domain"
name, so using it as a domain name doesn't give much benefits. This patch
adds support for human readable names defined in 'label' property. Such
names are visible to userspace and makes debugging much easier. When no
'label' property is found, driver keeps using the name constructed from
full node name.

The ACOK pin on the bq24735 is active-high, of course meaning that when
AC is OK the pin is high. However, all Tegra dts files have incorrectly
specified active-high even though the signal is inverted on the Tegra
boards. This has worked since the Linux driver has also inverted the
meaning of the GPIO. Fix this situation by simply specifying in the
bindings what everybody else agrees on; that the ti,ac-detect-gpios is
active on AC adapter absence.

Linus Torvalds 991688bfc6 ARM: SoC driver updates for v4.10 
Driver updates for ARM SoCs, including a couple of newly added drivers:
 
 - A new driver for the power management controller on TI Keystone
 - Support for the prerelease "SCPI" firmware protocol that ended up
   being shipped by Amlogic in their GXBB SoC.
 - A soc_device can now be matched using a glob from inside the
   kernel, when another driver wants to know the specific chip
   it is running on and cannot find out from DT, firmware or hardware.
 - Renesas SoCs now support identification through the soc_device
   interface, both in user space and kernel.
 - Renesas r8a7743 and r8a7745 gain support for their system controller
 - A new checking module for the ARM "PSCI" (not to be confused
   with "SCPI" mentioned above) firmware interface.
 - A new driver for the Tegra GMI memory interface
 - Support for the Tegra firmware interfaces with their
   power management controllers
 
 As usual, the updates for the reset controller framework are merged
 here, as they tend to touch multiple SoCs as well, including a new
 driver for the Oxford (now Broadcom) OX820 chip and the Tegra
 bpmp interface.
 
 The existing drivers for Atmel, Qualcomm, NVIDIA, TI Davinci, and
 Rockchips SoCs see some further updates.
 
 Conflicts:
 - ARCH_RENESAS now selects SOC_BUS, but no longer needs GPIOLIB
 - drivers/soc/renesas/Makefile: multiple files got added, keep
   all in logical sorting

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

Pull ARM SoC driver updates from Arnd Bergmann:
 "Driver updates for ARM SoCs, including a couple of newly added
  drivers:

   - A new driver for the power management controller on TI Keystone

   - Support for the prerelease "SCPI" firmware protocol that ended up
     being shipped by Amlogic in their GXBB SoC.

   - A soc_device can now be matched using a glob from inside the
     kernel, when another driver wants to know the specific chip it is
     running on and cannot find out from DT, firmware or hardware.

   - Renesas SoCs now support identification through the soc_device
     interface, both in user space and kernel.

   - Renesas r8a7743 and r8a7745 gain support for their system
     controller

   - A new checking module for the ARM "PSCI" (not to be confused with
     "SCPI" mentioned above) firmware interface.

   - A new driver for the Tegra GMI memory interface

   - Support for the Tegra firmware interfaces with their power
     management controllers

  As usual, the updates for the reset controller framework are merged
  here, as they tend to touch multiple SoCs as well, including a new
  driver for the Oxford (now Broadcom) OX820 chip and the Tegra bpmp
  interface.

  The existing drivers for Atmel, Qualcomm, NVIDIA, TI Davinci, and
  Rockchips SoCs see some further updates"

Lina Iyer 598da548ef PM / Domains: Fix compatible for domain idle state 
Re-using idle state definition provided by arm,idle-state for domain
idle states creates a lot of confusion and limits further evolution of
the domain idle definition. To keep things clear and simple, define a
idle states for domain using a new compatible "domain-idle-state".

Fix existing PM domains code to look for the newly defined compatible.

Linus Torvalds 043248cd4e ARM: DT updates for v4.8 
Device tree contents continue to be the largest branches we submit. This

   - Broadcom BCM23550
   - Cirrus Logic EP7209 and EP7211 (clps711x platforms)_
   - Hisilicon HI3519
   - Renesas R8A7792
 
 Some of the other delta that is sticking out, line-count wise:
  - Exynos moves of IP blocks under an SoC bus, which causes a large delta due
    to indentation changes
  - A new Tegra K1 board: Apalis
  - A bunch of small updates to many Allwinner platforms; new hardware support,
    some cleanup, etc.

 - Rewrite of the phandle args parsing code to get rid of the fixed args
   size.  This is needed for IOMMU code.

 - Sync to latest dtc which adds more dts style checking.  These
   warnings are enabled with "W=1" compiles.

 - Tegra documentation updates related to the above warnings.

 - A bunch of spelling and other doc fixes.

 - Various vendor prefix additions.

Linus Torvalds f7df9be067 ARM: DT updates for v4.7 
These are all the updates to device tree files for 32-bit platforms,
 which as usual makes up the bulk of the ARM SoC changes: 462 non-merge
 changesets, 450 files changed, 23340 insertions, 5216 deletions.
 
 The three platforms that are added with the "soc" branch are here as well,
 and we add some related machine files:
 
 - For Aspeed AST2400/AST2500, we get the evaluation platform and
   the Tyan Palmetto POWER8 mainboard that uses the AST2400 BMC
 - For Oxnas 810SE, the Western Digital "My Book World Edition"
   is added as the only platform at the moment.
 - For ARM MPS2, the AN385 (Cortex-M3) and AN399 (Cortex-M7)
   are supported
 
 On the ARM Realview development platform, we now support all machines
 with device tree, previously only the board files were supported, which
 in turn will likely be removed soon.
 
 Qualcomm IPQ4019 is the second generation ARM based "Internet Processor",
 following the IPQ806x that is used in many high-end WiFi routers. This one
 integrates two ath10k wifi radios that were previously on separate chips.
 
 Other boards that got added for existing chips are:
 
 - On Ti OMAP family:
   - Amazon Kindle Fire, first generation, tablet and ebook reader
   - OnRISC Baltos iR 2110 and 3220 embedded industrial PCs
   - TI AM5728 IDK, TI AM3359 ICE-V2, and TI DRA722 Rev C EVM

Linus Torvalds 1eccc6e152 This is the bulk of GPIO changes for kernel cycle v4.7: 
Core infrastructural changes:
 
 - Support for natively single-ended GPIO driver stages. This
   means that if the hardware has registers to configure open
   drain or open source configuration, we use that rather than
   (as we did before) try to emulate it by switching the line
   to an input to get high impedance. This is also documented
   throughly in Documentation/gpio/driver.txt for those of you
   who did not understand one word of what I just wrote.
 
 - Start to do away with the unnecessarily complex and
   unitelligible ARCH_REQUIRE_GPIOLIB and
   ARCH_WANT_OPTIONAL_GPIOLIB, another evolutional artifact from
   the time when the GPIO subsystem was unmaintained. Archs can
   now just select GPIOLIB and be done with it, cleanups to
   arches will trickle in for the next kernel. Some minor archs
   ACKed the changes immediately so these are included in this
   pull request.
 
 - Advancing the use of the data pointer inside the GPIO device
   for storing driver data by switching the PowerPC, Super-H
   Unicore and a few other subarches or subsystem drivers in
   ALSA SoC, Input, serial, SSB, staging etc to use it.
 
 - The initialization now reads the input/output state of the
   GPIO lines, so that each GPIO descriptor knows - if this
   callback is implemented - whether the line is input or
   output. This also reflects nicely in userspace "lsgpio".
 
 - It is now possible to name GPIO producer names, line names,
   from the device tree. (Platform data has been supported for
   a while.) I bet we will get a similar mechanism for ACPI
   one of those days. This makes is possible to get sensible
   producer names for e.g. GPIO rails in "lsgpio" in userspace.
 
 New drivers:
 
 - New driver for the Loongson1.
 
 - The XLP driver now supports Broadcom Vulcan ARM64.
 
 - The IT87 driver now supports IT8620 and IT8628.
 
 - The PCA953X driver now supports Galileo Gen2.
 
 Driver improvements:
 
 - MCP23S08 was switched to use the gpiolib irqchip helpers and
   now also suppors level-triggered interrupts.
 
 - 74x164 and RCAR now supports the .set_multiple() callback
 
 - AMDPT was converted to use generic GPIO.
 
 - TC3589x, TPS65218, SX150X, F7188X, MENZ127, VX855, WM831X, WM8994
   support the new single ended callback for open drain
   and in some cases open source.
 
 - Implement the .get_direction() callback for a few more drivers
   like PL061, Xgene.
 
 Cleanups:
 
 - Paul Gortmaker combed through the drivers and de-modularized
   those who are not really modules.
 
 - Move the GPIO poweroff DT bindings to the power subdir where
   they belong.
 
 - Rename gpio-generic.c to gpio-mmio.c, which is much more to the
   point. That's what it is handling, nothing more, nothing less.

Heiko Stuebner bc19b9a81d PM / AVS: rockchip-io: make io-domains a child of the GRF 
IO-domain handling is part of the general register files, so should live
under the grf directly. This change allows the grf to be a simple-mfd and
the io-domains fetching the syscon regmap from that parent-node.

The old binding is of course preserved, though deprecated.

Linus Torvalds 3d66c6ba3f Power management and ACPI material for v4.6-rc1, part 2 
- Fix for an intel_pstate driver issue related to the handling of
    MSR updates uncovered by the recent cpufreq rework (Rafael Wysocki).
 
  - cpufreq core cleanups related to starting governors and frequency
    synchronization during resume from system suspend and a locking
    fix for cpufreq_quick_get() (Rafael Wysocki, Richard Cochran).
 
  - acpi-cpufreq and powernv cpufreq driver updates (Jisheng Zhang,
    Michael Neuling, Richard Cochran, Shilpasri Bhat).
 
  - intel_idle driver update preventing some Skylake-H systems
    from hanging during initialization by disabling deep C-states
    mishandled by the platform in the problematic configurations (Len
    Brown).
 
  - Intel Xeon Phi Processor x200 support for intel_idle (Dasaratharaman
    Chandramouli).
 
  - cpuidle menu governor updates to make it always honor PM QoS
    latency constraints (and prevent C1 from being used as the
    fallback C-state on x86 when they are set below its exit latency)
    and to restore the previous behavior to fall back to C1 if the next
    timer event is set far enough in the future that was changed in 4.4
    which led to an energy consumption regression (Rik van Riel, Rafael
    Wysocki).
 
  - New device ID for a future AMD UART controller in the ACPI driver
    for AMD SoCs (Wang Hongcheng).
 
  - Rockchip rk3399 support for the rockchip-io-domain adaptive voltage
    scaling (AVS) driver (David Wu).
 
  - ACPI PCI resources management fix for the handling of IO space
    resources on architectures where the IO space is memory mapped
    (IA64 and ARM64) broken by the introduction of common ACPI
    resources parsing for PCI host bridges in 4.4 (Lorenzo Pieralisi).
 
  - Fix for the ACPI backend of the generic device properties API
    to make it parse non-device (data node only) children of an
    ACPI device correctly (Irina Tirdea).
 
  - Fixes for the handling of global suspend flags (introduced in 4.4)
    during hibernation and resume from it (Lukas Wunner).
 
  - Support for obtaining configuration information from Device Trees
    in the PM clocks framework (Jon Hunter).
 
  - ACPI _DSM helper code and devfreq framework cleanups (Colin Ian
    King, Geert Uytterhoeven).

Pull more power management and ACPI updates from Rafael Wysocki:
 "The second batch of power management and ACPI updates for v4.6.

  Included are fixups on top of the previous PM/ACPI pull request and
  other material that didn't make into it but still should go into 4.6.

  Among other things, there's a fix for an intel_pstate driver issue
  uncovered by recent cpufreq changes, a workaround for a boot hang on
  Skylake-H related to the handling of deep C-states by the platform and
  a PCI/ACPI fix for the handling of IO port resources on non-x86
  architectures plus some new device IDs and similar.

  Specifics:

   - Fix for an intel_pstate driver issue related to the handling of MSR
     updates uncovered by the recent cpufreq rework (Rafael Wysocki).

   - cpufreq core cleanups related to starting governors and frequency
     synchronization during resume from system suspend and a locking fix
     for cpufreq_quick_get() (Rafael Wysocki, Richard Cochran).

   - acpi-cpufreq and powernv cpufreq driver updates (Jisheng Zhang,
     Michael Neuling, Richard Cochran, Shilpasri Bhat).

   - intel_idle driver update preventing some Skylake-H systems from
     hanging during initialization by disabling deep C-states mishandled
     by the platform in the problematic configurations (Len Brown).

   - Intel Xeon Phi Processor x200 support for intel_idle
     (Dasaratharaman Chandramouli).

   - cpuidle menu governor updates to make it always honor PM QoS
     latency constraints (and prevent C1 from being used as the fallback
     C-state on x86 when they are set below its exit latency) and to
     restore the previous behavior to fall back to C1 if the next timer
     event is set far enough in the future that was changed in 4.4 which
     led to an energy consumption regression (Rik van Riel, Rafael
     Wysocki).

   - New device ID for a future AMD UART controller in the ACPI driver
     for AMD SoCs (Wang Hongcheng).

   - Rockchip rk3399 support for the rockchip-io-domain adaptive voltage
     scaling (AVS) driver (David Wu).

   - ACPI PCI resources management fix for the handling of IO space
     resources on architectures where the IO space is memory mapped
     (IA64 and ARM64) broken by the introduction of common ACPI
     resources parsing for PCI host bridges in 4.4 (Lorenzo Pieralisi).

   - Fix for the ACPI backend of the generic device properties API to
     make it parse non-device (data node only) children of an ACPI
     device correctly (Irina Tirdea).

   - Fixes for the handling of global suspend flags (introduced in 4.4)
     during hibernation and resume from it (Lukas Wunner).

   - Support for obtaining configuration information from Device Trees
     in the PM clocks framework (Jon Hunter).

   - ACPI _DSM helper code and devfreq framework cleanups (Colin Ian
     King, Geert Uytterhoeven)"

David Wu f447671b9e PM / AVS: rockchip-io: add io selectors and supplies for rk3399 
This adds the necessary data for handling io voltage domains on the rk3399.
As interesting tidbit, the rk3399 contains two separate iodomain areas.
One in the regular General Register Files (GRF) and one in PMUGRF in the
pmu power domain.

Linus Torvalds c0d6fe2f01 ARM: DT updates for v4.4 
As usual, this is the massive branch we have for each release. Lots of
 various updates and additions of hardware descriptions on existing hardware,
 as well as the usual additions of new boards and SoCs.
 
 This is also the first release where we've started mixing 64- and 32-bit
 DT updates in one branch.
 
 (Specific details on what's actually here and new is pretty easy to tell
 from the diffstat, so there's little point in duplicating listing it here.)

Currently different drivers use multiple forms of annotating devices
that should be set up as wakeup sources for the system.

This patch adds a separate binding document inorder to standardize and
consolidate to use "wakeup-source" boolean property to mark the devices
as wakeup capable.
