Merge tag 'pinctrl-v4.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control updates from Linus Walleij:
 "This is the bulk of pin control patches for the v4.5 series.

  Notably I have a patch to driver core from Stephen Boyd in the pull
  request, this has been ACKed by Greg so it should be OK.  The internal
  API needed some tweaking to allow modular Qualcomm pin controllers.

  There is a bit of development history in here but it should all add up
  nicely and has boiled in linux-next.  For example I merged in v4.4-rc5
  to get rid of some nasty merge conflicts.

  Summary:

   - New drivers:
      - PXA2xx pin controller support
      - Broadcom NSP pin controller support

   - New subdrivers:
      - Samsung EXYNOS5410 support
      - Qualcomm MSM8996 support
      - Qualcomm PM8994 support
      - Qualcomm PM8994 MPP support
      - Allwinner sunxi H3 support
      - Allwinner sunxi A80 support
      - Rockchip RK3228 support

   - Rename the Cygnus pinctrl driver to "iproc" as it is more generic
     than was originally thought.

   - A bunch of Lantiq/Xway updates especially from the OpenWRT people.

   - Several refactorings for the Super-H SH PFC pin controllers.
     Adding SCIF_CLK support.

   - Several fixes to the Atlas 7 driver.

   - Various fixes all over the place"

+
+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 arbitrary 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:
+
+- pins:
+	Usage: required
