Merge tag 'pinctrl-v3.17-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pinctrl updates from Linus Walleij:
 "This is the bulk pin control changes for the v3.17 merge development
  cycle:

   - get rid of the .disable() callback from the driver callback vtable.

     This callback was abused and counterintuitive since a pin or group
     of pins can be said to always be in some setting, and never really
     disabled.  We now only enable a certain muxing, and move between
     some certain muxings, we never "disable" a mux setting

   - some janitorial moving the MSM, Samsung and Nomadik and drivers to
     their own subdirectories for a clearer view in the subsystem.  This
     will continue

   - kill off the use of the return value from gpiochip_remove(), this
     will be done in parallel in the GPIO subsystem and hopefully not
     trigger too many unchecked return value warnings before we get rid
     of this altogether

   - a huge set of changes and improvements to the Allwinner sunxi
     drivers especially for their latest A23 and A31 SoCs, and some
     ground work for the new sun8i platform family

   - a large set of Rockchip driver improvements adding support for the
     RK3288 SoC

   - advances in migration of older Freescale platforms to pin control,
     especially i.MX1

   - Samsung and Exynos improvements

   - support for the Qualcomm MSM8960 SoC

   - use the gpiolib irqchip helpers for the ST SPEAr and Intel Baytrail
     drivers

   - a bunch of nice janitorial work done with cppcheck"

+Please refer to ../gpio/gpio.txt and ../interrupt-controller/interrupts.txt for
+a general description of GPIO and interrupt bindings.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+The pin configuration nodes act as a container for an abitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those pin(s)/group(s), and various pin configuration
+parameters, such as pull-up, drive strength, etc.
+
+
+PIN CONFIGURATION NODES:
+
+The name of each subnode is not important; all subnodes should be enumerated
+and processed purely based on their content.
+
+Each subnode only affects those parameters that are explicitly listed. In
+other words, a subnode that lists a mux function but no pin configuration
+parameters implies no information about any pin configuration parameters.
+Similarly, a pin subnode that describes a pullup parameter implies no
+information about e.g. the mux function.
+
+
+The following generic properties as defined in pinctrl-bindings.txt are valid
+to specify in a pin configuration subnode:
+
