[PATCH v6 0/7] Per-user clock constraints

[Tomeu Vizoso]

Hello,

this sixth version of the series has a small fix in the per-user clks commit
and the following changes in the clk constraints patch:

* Take the prepare lock before removing a per-user clk
* Init per-user clks list before adding the first clk
* Pass the constraints to determine_rate and let clk implementations deal
with constraints
* Add clk_set_rate_range

A rough test module was used to test this:

http://cgit.collabora.com/git/user/tomeu/linux.git/commit/?h=per-user-clk-constraints-v6&id=1bada453ab690a1c5be28667d94a4861bc84f8ef

The first five patches are just cleanups that should be desirable on their own,
and that should make easier to review the actual per-user clock patch.

The sixth patch actually moves the per-clock data that was stored in struct
clk to a new struct clk_core and adds references to it from both struct clk and
struct clk_hw. struct clk is now ready to contain information that is specific
to a given clk consumer.

The seventh patch adds API for setting floor and ceiling constraints and stores
that information on the per-user struct clk, which is iterable from struct
clk_core.

They are based on top of linux-next 20141128.

Thanks,

  clk: Remove unused function __clk_get_prepare_count
  clk: Don't try to use a struct clk* after it could have been freed
  clk: Don't expose __clk_get_accuracy
  clk: change clk_debugfs_add_file to take a struct clk_hw
  clk: Change clk_ops->determine_rate to return a clk_hw as the best
    parent
  clk: Make clk API return per-user struct clk instances
  clk: Add floor and ceiling constraints to clock rates
