Linus Torvalds 80fb974798 This is the bulk of GPIO changes for the v3.16 series:
- We are finalizing and fixing up the gpiochip irqchip helpers
   bringing a helpful irqchip implementation into the gpiolib
   core and avoiding duplicate code and, more importantly,
   duplicate bug fixes:
 
   - Support for using the helpers with threaded interrupt
     handlers as used on sleeping GPIO-irqchips
 
   - Do not set up hardware triggers for edges or levels if
     the default IRQ type is IRQ_TYPE_NONE - some drivers
     would exploit the fact that you could get default
     initialization of the IRQ type from the core at probe()
     but if no default type is set up from the helper, we
     should not call the driver to configure anything. Wait
     until a consumer requests the interrupt instead.
 
   - Make the irqchip helpers put the GPIO irqs into their
     own lock class. The GPIO irqchips can often emit
     (harmless, but annoying) lockdep warnings about recursions
     when they are in fact just cascaded IRQs. By putting
     them into their own lock class we help the lockdep core
     to keep track of things.
 
   - Switch the tc3589x GPIO expanders to use the irqchip
     helpers
 
   - Switch the OMAP GPIO driver to use the irqchip helpers
 
   - Add some documentation for the irqchip helpers
 
   - select IRQ_DOMAIN when using the helpers since some
     platforms may not be using this by default and it's a
     strict dependency.
 
 - Continued GPIO descriptor refactoring:
 
   - Remove the one instance of gpio_to_desc() from the
     device tree code, making the OF GPIO code use GPIO
     descriptors only.
 
   - Introduce gpiod_get_optional() and
     gpiod_get_optional_index() akin to the similar
     regulator functions for cases where the use of GPIO
     is optional and not strictly required.
 
   - Make of_get_named_gpiod_flags() private - we do not
     want to unnecessarily expose APIs to drivers that
     make the gpiolib harder than necessary to maintain
     and refactor. Privatize this function.
 
 - Support "-gpio" suffix for the OF GPIO retrieveal path.
   We used to look for "foo-gpios" or just "gpios" in device
   tree nodes, but it turns out that some drivers with a
   single GPIO line will just state "foo-gpio" (singularis).
   Sigh. Support this with a fallback looking for it, as
   this simplifies driver code and handles it in core code.
 
 - Switch the ACPI GPIO core to fetch GPIOs with the
   *_cansleep function variants as the GPIO operation
   region handler can sleep, and shall be able to handle
   gpiochips that sleep.
 
 - Tons of cleanups and janitorial work from Jingoo Han,
   Axel Lin, Javier Martinez Canillas and Abdoulaye Berthe.
   Notably Jingoo cut off a ton of pointless OOM messages.
 
 - Incremental development and fixes for various drivers,
   nothing really special here.

Merge tag 'gpio-v3.16-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio into next

Pull GPIO updates from Linus Walleij:
 "This is the bulk of GPIO changes for the v3.16 series.

  There is a lot of action in the GPIO subsystem doing refactorings and
  cleanups, almost as many deletions as insertions and minor feature
  growth and no new drivers this time.  Which is actually pretty nice.
  Some GPIO-related stuff will come in through the pin control tree as
  well.

  Details:

   - We are finalizing and fixing up the gpiochip irqchip helpers
     bringing a helpful irqchip implementation into the gpiolib core and
     avoiding duplicate code and, more importantly, duplicate bug fixes:

     * Support for using the helpers with threaded interrupt handlers as
       used on sleeping GPIO-irqchips

     * Do not set up hardware triggers for edges or levels if the
       default IRQ type is IRQ_TYPE_NONE - some drivers would exploit
       the fact that you could get default initialization of the IRQ
       type from the core at probe() but if no default type is set up
       from the helper, we should not call the driver to configure
       anything.  Wait until a consumer requests the interrupt instead.

     * Make the irqchip helpers put the GPIO irqs into their own lock
       class.  The GPIO irqchips can often emit (harmless, but annoying)
       lockdep warnings about recursions when they are in fact just
       cascaded IRQs.  By putting them into their own lock class we help
       the lockdep core to keep track of things.

     * Switch the tc3589x GPIO expanders to use the irqchip helpers

     * Switch the OMAP GPIO driver to use the irqchip helpers

     * Add some documentation for the irqchip helpers

     * select IRQ_DOMAIN when using the helpers since some platforms may
       not be using this by default and it's a strict dependency.

   - Continued GPIO descriptor refactoring:

     * Remove the one instance of gpio_to_desc() from the device tree
       code, making the OF GPIO code use GPIO descriptors only.

     * Introduce gpiod_get_optional() and gpiod_get_optional_index()
       akin to the similar regulator functions for cases where the use
       of GPIO is optional and not strictly required.

     * Make of_get_named_gpiod_flags() private - we do not want to
       unnecessarily expose APIs to drivers that make the gpiolib harder
       than necessary to maintain and refactor.  Privatize this
       function.

     off a ton of pointless OOM messages.
