Pull pin control changes from Linus Walleij:
 "This is the bulk of pin control changes for the v3.16 development
  cycle:

   - Antoine Tenart made the get_group_pins() vtable entry optional.

   - Antoine also provides an entirely new driver for the Marvell Berlin
     SoC.  This is unrelated to the existing MVEBU hardware driver and
     warrants its own separate driver.

   - reflected from the GPIO subsystem there is a number of refactorings
     to make pin control drivers with gpiochips use the new gpiolib
     irqchip helpers.  The following drivers were converted to use the
     new infrastructure:
       * ST Microelectronics STiH416 and friends
       * The Atmel AT91
       * The CSR SiRF (Prima2)
       * The Qualcomm MSM series

   - massive improvements in the Qualcomm MSM driver from Bjorn
     Andersson, Andy Gross and Kumar Gala.  Among those new support for
     the IPQ8064 and MSM8x74 SoC variants.

   - support for the Freescale i.MX6 SoloX SoC variant.

   - massive improvements in the Allwinner sunxi driver from Boris
     Brezillon, Maxime Ripard and Chen-Yu Tsai.

   - Renesas PFC updates from Laurent Pinchart, Kuninori Morimoto,
     Wolfram Sang and Magnus Damm.

   - Cleanups and refactorings of the nVidia Tegra driver from Stepgen
     Warren.

   - the Exynos driver now supports the Exynos3250 SoC.

   - Intel BayTrail updates from Jin Yao, Mika Westerberg.

   - the MVEBU driver now supports the Orion5x SoC variants, which is
     part of the effort of getting rid of the old Marvell kludges in
     arch/arm/mach-orion5x

   - Rockchip driver updates from Heiko Stuebner.

   - a ton of cleanups and janitorial patches from Axel Lin.

   - some minor fixes and improvements here and there"

+
+Qualcomm's 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.
+
+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:
+
+ pins, function, bias-disable, bias-pull-down, bias-pull,up, drive-strength,
+ output-low, output-high.
+
+Non-empty subnodes must specify the 'pins' property.
