      Merge branch 'depends/clk/clk-next' into next/clock · bef94596
      Arnd Bergmann authored 
      Mike Turquette <mturquette@ti.com> has asked me to take the clock
changes through the arm-soc tree while there are still so many
inderdependencies, so this is the entire branch.

* depends/clk/clk-next: (30 commits)
  clk: add a fixed factor clock
  clk: mux: assign init data
  clk: remove COMMON_CLK_DISABLE_UNUSED
  clk: prevent spurious parent rate propagation
  MAINTAINERS: add entry for common clk framework
  clk: clk_set_rate() must fail if CLK_SET_RATE_GATE is set and clk is enabled
  clk: Use a separate struct for holding init data.
  clk: constify parent name arrays in macros
  clk: remove trailing whitespace from clk.h
  clk: select CLKDEV_LOOKUP for COMMON_CLK
  clk: Don't set clk->new_rate twice
  clk: clk-private: Add DEFINE_CLK macro
  clk: clk-gate: Create clk_gate_endisable()
  clk: Fix typo in comment
  clk: propagate round_rate for CLK_SET_RATE_PARENT case
  clk: pass parent_rate into .set_rate
  clk: always pass parent_rate into .round_rate
  clk: basic: improve parent_names & return errors
  clk: core: copy parent_names & return error codes
  clk: Constify parent name arrays

      CLKDEV: provide helpers for common clock framework · e9d7f406
      Russell King authored 
      The common clock framework allocates clocks dynamically.  Provide a
set of helpers to streamline the clkdev registration of the clock
lookups to avoid repetitive code sequences.

      clk: clk_set_rate() must fail if CLK_SET_RATE_GATE is set and clk is enabled · 0e1c0301
      Viresh Kumar authored 
      This is well documented but isn't implemented. clk_set_rate() must check if
flags have CLK_SET_RATE_GATE bit set and is enabled too.

      clk: Use a separate struct for holding init data. · 0197b3ea
      Saravana Kannan authored 
      Create a struct clk_init_data to hold all data that needs to be passed from
the platfrom specific driver to the common clock framework during clock
registration. Add a pointer to this struct inside clk_hw.

This has several advantages:
* Completely hides struct clk from many clock platform drivers and static
  clock initialization code that don't care for static initialization of
  the struct clks.
* For platforms that want to do complete static initialization, it removed
  the need to directly mess with the struct clk's fields while still
  allowing to statically allocate struct clk. This keeps the code more
  future proof even if they include clk-private.h.
* Simplifies the generic clk_register() function and allows adding optional
  fields in the future without modifying the function signature.
* Simplifies the static initialization of clocks on all platforms by
  removing the need for forward delcarations or convoluted macros.

      clk: constify parent name arrays in macros · e447c50e
      Rajendra Nayak authored 
      parent name array is now expected to be const char *, make
the relevent changes in the clk macros which define
default clock types.

      pinctrl: add pinctrl_provide_dummies interface for platforms to use · 5b3aa5f7
      Dong Aisheng authored 
      Add a interface pinctrl_provide_dummies for platform to indicate
whether it needs use pinctrl dummy state.

ChangeLog v3->v4:
* remove dummy gpio support in pinctrl subsystem.
  Let gpio driver decide whether it wants to use pinctrl gpio mux
  function.
ChangeLog v2->v3:
* Also changed the missed pinctrl gpio APIs in v1.
ChangeLog v1->v2:
* Based on sascha's suggestion, drop using kconfig since it will hide
  pinctrl errors on all other boards.
  See: https://lkml.org/lkml/2012/4/18/282
  It seemed both Linus and Stephen agreed with this way, so i'm ok
  with it too.
* Add dummy gpio support.
  pinctrl gpio in the same situation as state.
* Patch name changed.
  Original is pinctrl: handle dummy state in core.
* Split removing old dt dummy interface into a separate patch
