ARM: SoC: device tree changes

A large part of the arm-soc patches are nowadays DT changes, adding support
for new SoCs, boards and devices without changing kernel source. The plan
is still to move the devicetree files out of the kernel tree and reduce
the amount of churn going on here, but we keep finding reasons to delay
doing that.

Changes are really all over the place, with little sticking out particularly.
We have contributions from a total of 116 people in this branch.

Unfortunately, the size of this branch also causes a significant number
of conflicts at the moment, typically when subsystem maintainers merge
patches that change the driver at the same time as the dts files. In
most cases this could be avoided because the dts changes are supposed
to be compatible in both ways, and we are asking everyone to send ARM
dts changes through our tree only.

ARM: SoC specific changes

Lots of changes specific to one of the SoC families. Some that
stick out are:

* mach-qcom gains new features, most importantly SMP support for
  the newer chips (Stephen Boyd, Rohit Vaswani)
* mvebu gains support for three new SoCs: Armada 375, 380 and 385
  (Thomas Petazzoni and Free-electrons team)
* SMP support for Rockchips (Heiko Stübner)
* Lots of i.MX changes (Shawn Guo)
* Added support for BCM5301x SoC (Hauke Mehrtens)
* Multiplatform support for Marvell Kirkwood and Dove
  (Andrew Lunn and Sebastian Hesselbarth doing the final part
  of a long journey)
* Unify davinci platforms and remove obsolete ones (Sekhar Nori,
  Arnd Bergmann)

ARM: SoC: cleanups for 3.15

These cleanup patches are mainly move stuff around and should all
be harmless. They are mainly split out so that other branches can
be based on top to avoid conflicts.

Notable changes are:

* We finally remove all mach/timex.h, after CLOCK_TICK_RATE is no
  longer used. (Uwe Kleine-König)
* The Qualcomm MSM platform is split out into legacy mach-msm and
  new-style mach-qcom, to allow easier maintainance of the new
  hardware support without regressions. (Kumar Gala)
* A rework of some of the Kconfig logic to simplify multiplatform
  support (Rob Herring)
* Samsung Exynos gets closer to supporting multiplatform (Sachin
  Kamat and others)
* mach-bcm3528 gets merged into mach-bcm (Stephen Warren)
* at91 gains some common clock framework support (Alexandre Belloni,
  Jean-Jacques Hiblot and other French people).

ARM: SoC non-critical bug fixes for 3.15

Lots of isolated bug fixes that were not found to be important
enough to be submitted before the merge window or backported
into stable kernels.
The vast majority of these came out of Arnd's randconfig testing
and just prevents running into build-time bugs in configurations
that we do not care about in practice.

- cmd parser for gen7 but only in enforcing and not yet granting mode - the
  batch copying stuff is still missing. Also performance is a bit ... rough
  (Brad Volkin + OACONTROL fix from Ken).
- deprecate UMS harder (i.e. CONFIG_BROKEN)
- interrupt rework from Paulo Zanoni
- runtime PM support for bdw and snb, again from Paulo
- a pile of refactorings from various people all over the place to prep for new
  stuff (irq reworks, power domain polish, ...)

This is the 3.13.9 stable release

This is the 3.10.36 stable release

This is the 3.4.86 stable release

This is the bulk of GPIO changes for v3.15:

- Merged in a branch of irqchip changes from Thomas
  Gleixner: we need to have new callbacks from the
  irqchip to determine if the GPIO line will be eligible
  for IRQs, and this callback must be able to say "no".
  After some thinking I got the branch from tglx and
  have switched all current users over to use this.

- Based on tglx patches, we have added some generic
  irqchip helpers in the gpiolib core. These will
  help centralize code when GPIO drivers have simple
  chained/cascaded IRQs. Drivers will still define
  their irqchip vtables, but the gpiolib core will
  take care of irqdomain set-up, mapping from local
  offsets to Linux irqs, and reserve resources by
  marking the GPIO lines for IRQs.

- Initially the PL061 and Nomadik GPIO/pin control
  drivers have been switched over to use the new
  gpiochip-to-irqchip infrastructure with more
  drivers expected for the next kernel cycle. The
  factoring of just two drivers still makes it worth
  it so it is already a win.

- A new driver for the Synopsys DesignWare APB GPIO
  block.

- Modify the DaVinci GPIO driver to be reusable also
  for the new TI Keystone architecture.

- A new driver for the LSI ZEVIO SoCs.

- Delete the obsolte tnetv107x driver.

- Some incremental work on GPIO descriptors: have
  gpiod_direction_output() use a logical level,
  respecting assertion polarity through ACTIVE_LOW
  flags, adding gpiod_direction_output_raw() for the
  case where you want to set that very value. Add
  gpiochip_get_desc() to fetch a GPIO descriptor from
  a specific offset on a certain chip inside driver
  code.

- Switch ACPI GPIO code over to using
  gpiochip_get_desc() and get rid of gpio_to_desc().

- The ACPI GPIO event handling code has been reworked
  after encountering an actual real life implementation.

- Support for ACPI GPIO operation regions.

- Generic GPIO chips can now be assigned labels/names
  from platform data.

- We now clamp values returned from GPIO drivers to
  the boolean [0,1] range.

- Some improved documentation on how to use the polarity
  flag was added.

- The a large slew of incremental driver updates and
  non-critical fixes. Some targeted for stable.

This is the 3.12.16 stable release

This is the 3.2.56 stable release

This is the 3.13.8 stable release

This is the 3.10.35 stable release

Pin control bulk changes for the v3.15 series, no new core
functionality this time, just incremental driver updates:

- A large refactoring of the MVEBU (Marvell) driver.

- A large refactoring of the Tegra (nVidia) driver.

- GPIO interrupt including soft edges support in the
  STi driver.

- Misc updates to PFC (Renesas), AT91, ADI2 (Blackfin),
  pinctrl-single, sirf (CSR), msm (Qualcomm), Exynos (Samsung),
  sunxi (AllWinner), i.MX (Freescale), Baytrail.
