Subject: [PATCH v4 0/8] Per-user clock constraints


this fourth version of the series is mainly intended to address many good
comments from Stephen Boyd, most notably:

* Make sure that best_parent_p is populated with the current parent before
calling clk_ops.determine_rate()

* Make sure we don't lose information about the caller in of_clk_get_*

* Refresh the effective rate after a per-user clk is removed

* Store requested rate and re-apply it when constraints are updated

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

They are based on top of 3.18-rc1.



Tomeu Vizoso (8):
  MIPS: Alchemy: Remove direct access to prepare_count field of struct
  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
  clk: Make clk API return per-user struct clk instances
  clk: Add floor and ceiling constraints to clock rates
