Linus Torvalds 06b49ea43c This is the bulk of GPIO changes for the v3.17 development
cycle, and this time we got a lot of action going on and
 it will continue:
 
 - The core GPIO library implementation has been split up in
   three different files:
   - gpiolib.c for the latest and greatest and shiny GPIO
     library code using GPIO descriptors only
   - gpiolib-legacy.c for the old integer number space API
     that we are phasing out gradually
   - gpiolib-sysfs.c for the sysfs interface that we are
     not entirely happy with, but has to live on for
     ABI compatibility
 
 - Add a flags argument to *gpiod_get* functions, with some
   backward-compatibility macros to ease transitions. We
   should have had the flags there from the beginning it
   seems, now we need to clean up the mess. There is a plan
   on how to move forward here devised by Alexandre Courbot
   and Mark Brown.
 
 - Split off a special <linux/gpio/machine.h> header for the
   board gpio table registration, as per example from the
   regulator subsystem.
 
 - Start to kill off the return value from gpiochip_remove()
   by removing the __must_check attribute and removing all
   checks inside the drivers/gpio directory. The rationale
   is: well what were we supposed to do if there is an error
   code? Not much: print an error message. And gpiolib already
   does that. So make this function return void eventually.
 
 - Some cleanups of hairy gpiolib code, make some functions
   not to be used outside the library private and make sure
   they are not exported, remove gpiod_lock/unlock_as_irq()
   as the existing function is for driver-internal use and
   fine as it is, delete gpio_ensure_requested() as it is
   not meaningful anymore.
 
 - Support the GPIOF_ACTIVE_LOW flag from gpio_request_one()
   function calls, which is logical since this is already
   supported when referencing GPIOs from e.g. device trees.
 
 - Switch STMPE, intel-mid, lynxpoint and ACPI (!) to use
   the gpiolib irqchip helpers cutting down on GPIO irqchip
   boilerplate a bit more.
 
 - New driver for the Zynq GPIO block.
 
 - The usual incremental improvements around a bunch of
   drivers.
 
 - Janitorial syntactic and semantic cleanups by Jingoo Han,
   and Rickard Strandqvist especially.
