Hello,
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 clk_core.
They are based on top of 3.18-rc1.

Thanks,

Tomeu Vizoso (8): MIPS: Alchemy: Remove direct access to prepare_count field of struct clk 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
