[PATCH v3 0/6] Add generic set_rate clk_ops for PLL35xx and PLL36xx for samsung SoCs

This patch series does the following: 

 1) Factors out possible common code, unifies the clk strutures used
    for PLL35xx & PLL36xx and usues clk->base instead of clk->con0

 2) Defines a common rate_table which will contain recommended p, m, s and k
    values for supported rates that needs to be changed for changing
    corresponding PLL's rate

 3) Adds set_rate() and round_rate() clk_ops for PLL35xx and PLL36xx

changes since v2:
	- Added new patch to reorder the MUX registration for mout_vpllsrc MUX
	before the PLL registrations. And to add the alias for the mout_vpllsrc MUX.
        - Added a check to confirm parent rate while registrating the PLL
	rate tables.

changes since v1:
	- removed sorting and bsearch
	- modified the definition of struct "samsung_pll_rate_table"
	- added generic round_rate()
	- rectified the ops assignment for "rate table passed as NULL"
	  during PLL registration

Is rebased on branch kgene's "for-next"
https://git.kernel.org/cgit/linux/kernel/git/kgene/linux-samsung.git/log/?h=for-next

And tested these patch on chromebook for EPLL settings for Audio on our chrome tree.


Vikas Sajjan (3):
  clk: samsung: Add set_rate() clk_ops for PLL36xx
  clk: samsung: Add alias for mout_vpllsrc and reorder MUX registration
    for it
  clk: samsung: Add EPLL and VPLL freq table for exynos5250 SoC

Yadwinder Singh Brar (3):
  clk: samsung: Use clk->base instead of directly using clk->con0 for
    PLL3xxx
  clk: samsung: Add support to register rate_table for PLL3xxx
  clk: samsung: Add set_rate() clk_ops for PLL35xx
