GPIO tree bulk changes for v3.14

A big set this merge window, as we have much going on in
this subsystem. Major changes this time:

- Some core improvements and cleanups to the new GPIO
  descriptor API. This seems to be working now so we can
  start the exodus to this API, moving gradually away from
  the global GPIO numberspace.

- Incremental improvements to the ACPI GPIO core, and move
  the few GPIO ACPI clients we have to the GPIO descriptor
  API right *now* before we go any further. We actually
  managed to contain this *before* we started to litter
  the kernel with yet another hackish global numberspace for
  the ACPI GPIOs, which is a big win.

- The RFkill GPIO driver and all platforms using it have
  been migrated to use the GPIO descriptors rather than
  fixed number assignments. Tegra machine has been migrated
  as part of this.

- New drivers for MOXA ART, Xtensa GPIO32 and SMSC SCH311x.
  Those should be really good examples of how I expect a
  nice GPIO driver to look these days.

- Do away with custom GPIO implementations on a major
  part of the ARM machines: ks8695, lpc32xx, mv78xx0.
  Make a first step towards the same in the horribly
  convoluted Samsung S3C include forest. We expect to
  continue to clean this up as we move forward.

- Flag GPIO lines used for IRQ on adnp, bcm-kona, em,
  intel-mid and lynxpoint.
  This makes the GPIOlib core aware that a certain GPIO line
  is used for IRQs and can then enforce some semantics such
  as disallowing a GPIO line marked as in use for IRQ to be
  switched to output mode.

- Drop all use of irq_set_chip_and_handler_name().
  The name provided in these cases were just unhelpful
  tags like "mux" or "demux".

- Extend the MCP23s08 driver to handle interrupts.

- Minor incremental improvements for rcar, lynxpoint, em
  74x164 and msm drivers.

- Some non-urgent bug fixes here and there, duplicate
  #includes and that usual kind of cleanups.

GPIO fixes for the v3.13 development cycle:

- Driver bug fixes for SH PFC, TWL4030, MSM and RCAR.

- Update the MAINTAINERS

GPIO fixes for the v3.13 series:

- Fix compile warnings.

- Fix overly talkative diagnostic messages from usual use
  cases wrt GPIO descriptors.

- Add a documentation 00-INDEX

- Use platform GPIOs as fallback when ACPI or device tree is
  used as the primary means to get GPIO lines.

- A bug fix for the MPC8572/MPC8536 fixing erroneous input data.

GPIO fixes for the v3.13 series:

- A big slew of documentation for the gpiod transition that
  happened in the merge window, no semantic effect, but we should
  provide proper documentation with the new API.

- Fix flags related to the new API.

- Fix to the find_chip_by_name() lookup function related to the
  new API.

- Fix of_find_gpio() when not using device tree.

- Bug fix for the TB10x direction setting.

- Error path fixes from Dan Carpenter.

- Nasty IRQdomain bug relating to taking an unitialized spinlock.

- Minor fixes here and there.

GPIO bulk changes for the v3.13 development cycle

- Merged the GPIO descriptor API from Alexandre Courbot.
  This is a first step toward trying to get rid of the
  global GPIO numberspace for the future.

- Add an API so that driver can flag that a certain GPIO
  line is being used by a irqchip backend for generating
  IRQs, so that we can enforce checks, like not allowing
  users to switch that line to an output at runtime, since
  this makes no sense. Implemented corresponding calls
  in a few select drivers.

- ACPI GPIO cleanups, refactorings and switch to using the
  descriptor-based interface.

- Support for the TPS80036 Palmas GPIO variant.

- A new driver for the Broadcom Kona GPIO SoC IP block.

- Device tree support for the PCF857x driver.

- A set of ARM GPIO refactorings with the goal of getting
  rid of a bunch of custom GPIO implementations from the
  arch/arm/* tree:

  - Move the IOP GPIO driver to the GPIO subsystem and
    fix all users to use the gpiolib API for accessing
    GPIOs. Delete the old custom GPIO implementation.

  - Delete the unused custom PXA GPIO implemention.

  - Convert all users of the IXP4 custom GPIO
    implementation to use gpiolib and delete the custom
    implementation.

  - Delete the custom Gemini GPIO implementation, also
    completely unused.

- Various cleanups and renamings.

Three GPIO fixes for the v3.12 series:
- A fix to the Lynxpoint IRQ handler
- Two late fixes to fallout from the gpiod refactoring

Fixes for the GPIO tree for v3.12:
- Two patches for the OMAP driver, dealing with setting up IRQs
  properly on the device tree boot path.

This is the bulk of GPIO changes for the v3.12 series:

- A new driver for the TZ1090 PDC which is used on the metag
  architecture.

- A new driver for the Kontron ETX or COMexpress GPIO block.
  This is found on some ETX x86 devices.

- A new driver for the Fintek Super-I/O chips, used on
  some x86 boards.

- Added device tree probing on a few select GPIO blocks.

- Drop the Exynos support from the Samsung GPIO driver.
  The Samsung maintainers have moved over to use the
  modernized pin control driver to provide GPIO for the
  modern platforms instead.

- The usual bunch of non-critical fixes and cleanups.
