regulator: Updates for v4.2

Another fairly quiet release, some new drivers with generic handling for
minor features but nothing that makes a substantial difference outside
of the subsystem or for most boards:

 - Support for a bunch of new parameters which are present on enough
   regulators to be worth having generic handling for in the framework.
 - Fixes for some issues with printing constraints during boot which
   should probably have gone in for v4.1 but didn't.
 - New drivers for Dialog DA9062, Maxim MAX77621 and Qualcomm SPMI regulators.

DeviceTree updates for 4.2:

- dtc import script improvements and sync with upstream dtc.

- Make CONFIG_OF user selectable enabling overlays and unittests on any
architecture.

- Constify FDT blob pointers.

- Add driver helper to directly match and return match data.

- Various DT binding documentation updates.

IOMMU Updates for Linux v4.2

This time with bigger changes than usual:

	* A new IOMMU driver for the ARM SMMUv3. This IOMMU is pretty
	  different from SMMUv1 and v2 in that it is configured through
	  in-memory structures and not through the MMIO register region.
	  The ARM SMMUv3 also supports IO demand paging for PCI devices
	  with PRI/PASID capabilities, but this is not implemented in
	  the driver yet.

	* Lots of cleanups and device-tree support for the Exynos IOMMU
	  driver. This is part of the effort to bring Exynos DRM support
	  upstream.

	* Introduction of default domains into the IOMMU core code. The
	  rationale behind this is to move functionalily out of the
	  IOMMU drivers to common code to get to a unified behavior
	  between different drivers.
	  The patches here introduce a default domain for iommu-groups
	  (isolation groups). A device will now always be attached to a
	  domain, either the default domain or another domain handled by
	  the device driver. The IOMMU drivers have to be modified to
	  make use of that feature. So long the AMD IOMMU driver is
	  converted, with others to follow.

	* Patches for the Intel VT-d drvier to fix DMAR faults that
	  happen when a kdump kernel boots. When the kdump kernel boots
	  it re-initializes the IOMMU hardware, which destroys all
	  mappings from the crashed kernel. As this happens before
	  the endpoint devices are re-initialized, any in-flight DMA
	  causes a DMAR fault. These faults cause PCI master aborts,
	  which some devices can't handle properly and go into an
	  undefined state, so that the device driver in the kdump kernel
	  fails to initialize them and the dump fails.
	  This is now fixed by copying over the mapping structures (only
	  context tables and interrupt remapping tables) from the old
	  kernel and keep the old mappings in place until the device
	  driver of the new kernel takes over. This emulates the the
	  behavior without an IOMMU to the best degree possible.

	* A couple of other small fixes and cleanups.

This is the 4.0.6 stable release

This is the 3.14.45 stable release

This is the 3.10.81 stable release

ASoC: A couple more updates for v4.2

These were sitting on my laptop.

ASoC: Further updates for v4.2

There's a bunch of additional updates and fixes that came in since my
orignal pull request here, including DT support for rt5645 and fairly
large serieses of cleanups and improvements to tas2552 and rcar.

This is the big bulk of GPIO changes queued for the v4.2
kernel series:

- A big set of cleanups to the aged sysfs interface from
  Johan Hovold. To get these in, v4.1-rc3 was merged into
  the tree as the first patch in that series had to go
  into stable. This makes the locking much more fine-grained
  (get rid of the "big GPIO lock(s)" and store states in the
  GPIO descriptors.

- Rename gpiod_[g|s]et_array() to gpiod_[g|s]et_array_value()
  to avoid confusions.

- New drivers for:
  - NXP LPC18xx (currently LPC1850)
  - NetLogic XLP
  - Broadcom STB SoC's
  - Axis ETRAXFS
  - Zynq Ultrascale+ (subdriver)

- ACPI:
  - Make it possible to retrieve GpioInt resources from
    a GPIO device using acpi_dev_gpio_irq_get()
  - Merge some dependent I2C changes exploiting this.
  - Support the ARM X-Gene GPIO standby driver.

- Make it possible for the generic GPIO driver to read
  back the value set registers to reflect current
  status.

- Loads of OMAP IRQ handling fixes.

- Incremental improvements to Kona, max732x, OMAP, MXC, RCAR,
  PCA953x, STP-XWAY, PCF857x, Crystalcove, TB10x.

- Janitorial (contification, checkpatch cleanups)

- refactoring hpd irq handlers (Jani)
- polish skl dpll code a bit (Damien)
- dynamic cdclk adjustement (Ville & Mika)
- fix up 12bpc hdmi and enable it for real again (Ville)
- extend hsw cmd parser to be useful for atomic configuration (Franscico Jerez)
- even more atomic conversion and rolling state handling out across modeset code
  from Maarten & Ander
- fix DRRS idleness detection (Ramalingam)
- clean up dsp address alignment handling (Ville)
- some fbc cleanup patches from Paulo
- prevent hard-hangs when trying to reset the gpu on skl (Mika)

sound fixes for 4.1-final

Nothing looks scary, just a few usual HD-audio regression fixes
and fixup, in addition to a minor Kconfig dependency fix for
the old MIPS drivers.

This is the 3.4.108 stable release
