Some platform has provision to change cpu parent clock during
cpu frequency scaling. This patch series provides a mechanism to
implement the same using CCF.

Patch1 provides mechanism to migrate to new parent temporarily.

Patch2 updates the user of clk_register_mux and DEFINE_CLK_MUX which are
modified to add support for clk migration.

Patch3 adds support to Exynos5250 to use the clock parent migration feature
implemented in CCF.

Changes in v2:
	- Renamed flag name from CLK_SET_RATE_ALTERNATE to CLK_SET_RATE_TEMP_PARENT
	- Renamed "alternate_parent_name" to "temp_parent_name" and
	  "alternate_parent" to "temp_parent"

Chander Kashyap (3):
  clk: add support for temporary parent clock migration
  clk: update users of "clk_register_mux" and "DEFINE_CLK_MUX"
  clk: samsung: Exynos5250: Add alternate parent name for mout_cpu
