Linus Torvalds 154d6f18a4 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.

Pull bulk of gpio updates from Linus Walleij:
 "A pretty big chunk of changes this time, but it has all been on
