[PATCH V4 0/3] clk: Fixup issues for clk_set_parent

[Ulf Hansson]

From: Ulf Hansson <ulf.hansson at linaro.org>

These issues exist in the clk_set_parent API:

* Race issue for spinlocks when updating the clock tree toplogy.
* The feature of reparent to the orphan list is broken.

This patchset fixes both problems. Patch 1 prepares for patch 2 and
patch 3, which are where the real issues are resolved.

Changes in v4:
	- Rebased on top Mike's clk reentrancy patches.

Changes in v3:
	- Fix review comments from Mike.
	- Include fixup for allow reparent to the orphan list.

Changes in v2:
	- Do not remove the existing __clk_reparent API.
	- Rebase patches.

Ulf Hansson (3):
  clk: Restructure code for __clk_reparent
  clk: Fixup errorhandling for clk_set_parent
  clk: Fixup locking issues for clk_set_parent
